Ah that looks hard im in geometry honors so i’ll try to explain it
Answer:
The roots are -2 and -3
Step-by-step explanation:
In the function x² + bx + c, <em>a</em> is equal to 1, then the factored form of this function is: (x - x1)*(x - x2) where x1 and x2 are the roots.
Wilma got the following expression:
(x - 1)*(x - 6) = x² - 6x - x + 6 = x² - 7x + 6, where '+6' is correct but '-7x' is incorrect.
Greg got the following expression:
(x + 1)*(x + 4) = x² + 4x + x + 4 = x² + 5x + 4, where '+5x' is correct but '+4' is incorrect.
Therefore the quadratic equation is: x² + 5x + 6. Its roots are:
X-3/8=-1/4
+3/8
x=-1/4+3/8
make both bottom numbers the same so you are able to add them
-1/4×2/2= -2/8
x=-2/8+3/8
x=1/8
I think the orginal expression is -27z^2-4z^2
But in simplified form it's -31z^2
