(3x −5)^2 =(? + ?? +25)

x = 3.556 or

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:

(3*x-5)^2-((x+x+25))=0

Evaluate:  

=

Pull like factors:

9x^2 - 32x  =   x • (9x - 32)

 x • (9x - 32)  = 0

Remember roots of a product:

A product of several terms equals zero. When a product of two or more terms equals zero, then at least one of the terms must be zero. We shall now solve each term = 0 separately. In other words, we are going to solve as many equations as there are terms in the product. Any solution of term = 0 solves product = 0 as well.

Solve  :    9x - 32 = 0

Add  32  to both sides of the equation :

                     9x = 32

Divide both sides of the equation by 9:

                    x = 32/9 = 3.556

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
