Answer:
x = ±2
Step-by-step explanation:
9x^2-36=0
Using the square root property
9x^2 = 36
Divide each side by 9
x^2 = 4
Take the square root of each side
sqrt(x^2) = sqrt(4)
x = ±2
You can only add/subtract like terms so:
2a+ab+2b+4a^2-3ab+9
2a-2ab+2b+4a^2+9 (the only like terms were ab and -3ab)
