(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

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
