Answer: true
Step by step-
Ok so
we don't know the sign so it could be
4x^2-8x+60 or
4x^2-8x-60
( if it is the first one, go to AAAAAAA
if it is second one go to BBBBBBBBBBB)
to find the zero fo the function, set the fnction to zero
then factor since if you had xy=0, then assume that x and y=0
AAAAAAAAAA
4x^2-8x+60=0
4(x^2-2x+15)=0
4 you get a nonreal root so the missing sign is probably a negative sign
if you were to graph this one, there is no x intercept
BBBBBBBBB
4x^2-8x-60=0
4(x^2-2x-15)=0
4(x-5)(x-3)=0
x-5=0
x=5
x-3=0
x=3
3<5
smallest zero is 3
I would say the smallest zero is 3
Answer:
149-1
Step-by-step explanation:
if you did 149-1 you'd get 148
Answer:
2x⁶ + 16x⁵ + 30x⁴
Step-by-step explanation:
area of rectangle with height 2x⁴ and width x²+8x+15
area = height x width
2x⁴( x²+8x+15)
2x⁴( x²) +2x⁴(8x)+ 2x⁴(15)
2x⁴⁺² + 16x⁴⁺¹ + 30x⁴
2x⁶ + 16x⁵ + 30x⁴
the area of the rectangle in polynomial which is in standardised form is 2x⁶ + 16x⁵ + 30x⁴
