Answer:
x=2
x=-5
Step-by-step explanation:
You need to get everything on one side to have a quadratic equation:
x^2+6x-4 -(3x+6) = x^2+3x-10
All factors of 10 are 1*10 and 2*5.
5-2 = 3 and 5*-2 = -10
Factoring x^2+3x-10 gives us (x-2)(x+5)
x=2
x=-5
Answer:
x=-5 x=2
Step-by-step explanation:
x^2+ 6x - 4 = 3x + 6
Subtract 3x from each side
x^2+ 6x-3x - 4 = 3x-3x + 6
x^2+ 3x - 4 = 6
Subtract 6 from each side
x^2+ 3x - 4-6 = 6 - 6
x^2 +3x -10 =0
Factor
What 2 numbers multiply to -10 and add to 3
5*-2 =-10
5+-2 = 3
(x+5) (x-2) =0
Using the zero product property
x+5 =0 x-2 =0
x=-5 x=2
