Answer:
2x^2+4x-16
Step-by-step explanation:
The quadratic can be written as
f(x) = a(x-z1)(x-z2) where z1 and z2 are the roots
f(x) = a (x-2)(x- -4)
a is the leading coefficient
f(x) = 2(x-2)(x+4)
= 2(x^2 -2x+4x-8)
= 2(x^2 +2x-8)
= 2x^2 +4x-16
$60.00
you subtract the original number with the new number to see the difference.
Put them all in your calculator and it will show you which is correct
It is between 13 and 13.5
Well 13^2 = 169 and 13.5^2 = 182.25
