To me that is the answer I do not understand the options u put down 6/386 = 64.33
4x2-36=0
+36 +36
4x2=36
Divide by 4
X2=9
Square root of x2 is x and the square root of 9 is 3
X=3
To factor x^2+5x-24:
Set up parentheses,
x * x = x^2 so x in beginnig of each parenthesis
What numbers multiply into -24 and add up to 5? 8*(-3)=24 8-3=5
(x+8)(x-3)
