Question

Which of the following are solutions to the equation? (check all that apply)
a. -6
b. -5
c.6
d.4
e.-2
f.5

Answer 1

whoops the equation is x2-3x+27=8x-3

Answer 2

is that x squared or 2x?

Answer 3

x squared

Answer 4

ok so first you move the 8x to the other side and it becomes negative, so when you combine -8x-3x=-11x. do the same with the negative 3 and it becomes positive, so you get 27+3=30.

Answer 5

The next step is to factor. so you are left with x^2-11x+30=0. when you factor, you get (x-6) (x-5)=0 so x-6=0 and x-5=0. by solving these equations the answers are 6 and 5

Answer 6

thank you so much!
