Answer:

x^2=8x-35

Explanation:

1.1 Factoring x2-8x+35

The first term is, x2 its coefficient is 1 .

The middle term is, -8x its coefficient is -8 .

The last term, "the constant", is +35

Step-1 : Multiply the coefficient of the first term by the constant 1 • 35 = 35

Step-2 : Find two factors of 35 whose sum equals the coefficient of the middle term, which is -8 .

-35 + -1 = -36

-7 + -5 = -12

-5 + -7 = -12

-1 + -35 = -36

1 + 35 = 36

5 + 7 = 12

7 + 5 = 12

35 + 1 = 36
