Write the quadratic equation whose roots are - 4 and 1, and whose leading coefficient is 4

y = 4 (x+4) (x-1)

Step-by-step explanation:

Since the leading coefficient is 4, put that in front of the parentheses.

The root - 4 must be added to x to be graphed correctly. The root 1 must be subtracted from x to be graphed correctly.

y = 4 (x+4) (x-1)
