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
Example:
9.075= 9+ 0/10 + 7 + 100+ 5/1000
=9000/1000 + 0/1000 + 70/1000 + 5/1000
=9075/1000
