Answer:
1, -6
Step-by-step explanation:
Easiest is just to factor
(x+1)(x-6)=0
24 / 30 x 100 = 80
answer: <span>Twenty-four is 30% of 80</span>
14 hours
672 miles / 48 mph = 14 hours total
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
