Question

An equation is given.

5x² - 60x + 135 = (x - 6)2 – 7x + 12
Which of the following is a factor that can be used to find the solution to the given equation?

A.(x+7)
B.(x-1)
C.(x-3)
D.(x-18)​

Answer 1

5x-60x+135=(x-6)2-7x+12

grouping like terms

5x-60x+7x-x=-6+2+12-135

-49x=8-135

-49x=-127

-49x/49=-127/49

x= -2.59
