If you are looking for the zeros of this function: x = -2 plus or minus 2 X the square root of 5.

As an example, the product of (a + b) (a - b) is equal to a squared - b squared."Special product" simply means that there are special cases, when multiplying polynomials, that are worth memorizing. For example, if you know the above, then you can easily start factoring any expression that contains the difference of two perfect squares - for example, x squared minus 1, a to the power 6 minus b to the power 4, or even - if you start using complex numbers - a squared + b squared = a squared - (-1) b squared.

If you mean: x squared -x -56 = 0 then using the quadratic equation formula x = 8 or x = -7

Using the quadratic formula-- ((negative b plus or minus the square root of b squared minus 4ac) divided by (2a)) you'll want to google that so you can see it in numerical form. a, b, and c are the coefficiants of your three terms ( 2 is a, -5 is b, and 2 is c) The answer is (x-2)(2x-1).

Using the quadratic formula you get z≅4.91547594742265 or z≅-0.91547594742265

Pythagoras' theorem states that for any right angle triangle the square of its hypotenuse is equal to the sum of its squared sides as in the following formula:- a squared + b squared = c squared whereas a and b are the sides of the triangle with c being its hypotenuse

4 times 4 minus 4 minus square root of 4.

No but the sum of the squared sides will equal the square of the hypotenuse using Pythagoras' theorem for a right angle triangle

Solve using the quadratic formula

using the pythagoren therum, a squared +b squared=c squared, if you are finding the hypotenuse square the other to sides and divide the answer to get the length of the hypotenuse otherwise square the hypotenuse and the known side and subtract the known side squared from the hypotenuse squared to find the lenght of the unknown side squared

It can be solved by using the quadratic equation formula.

1 square metre is equal to 3.25 feet squared, so simply divide 650 by (3.25 x 3.25) to give the answer, which is 61.54 square metres. (2 d.p.) That is based on using the U.K. imperial foot, which also equals 12 U.K. inches.

Using the quadratic formula to solve any quadratic equation is the best way of getting around it because the quadratic formula is "the opposite of b plus or minus the square root of b squared minus 4ac all divided by 2a. This formula only works with trinomials and second degree equaitons. If the equation is a binomial, then put in a placeholer (0) and substitute them into the equation.

Pythagoras' theorem states that for any right angle triangle that the square of its hypotenuse is equal to the sum of its squared sides or a^2 + b^2 = c^2 whereas a and b are the sides with c being the hypotenuse.

Using the discriminant for a quadratic equation the value of k works out as plus or minus 12.
