The roots would be x=-5 and x=-4 but with that website you just do -5 and -4
Answer:
x² + 10x - 24
Step-by-step explanation:
Given the roots are x = - 12 and x = 2 then the corresponding factors are
(x + 12) and (x - 2) and their product equals zero , that is
(x + 12)(x - 2) = 0 ← expand using FOIL
X² + 10X - 24 = 0
Expanded form is when you just write it out.
so 9 cubed becomes:
9×9×9
and 20 squared becomes:
20×20
the exponent tells you how many times to multiply that number by itself. so, whenever it asks for expanded form, you just write the number how ever many times the exponent tells you to and multiply them all.
