Answer:
X Intercept (-2,0), (-3,0) and Standard form y = -4x^2 - 20x - 24
Step-by-step explanation:
To write a polynomial in standard form, simplify, and then arrange the terms in descending order.
y = ax^2 + bx + c
y = (−4x−8) (x+3)
Expand (−4x−8) (x+3) using the FOIL Method
y = −4x ⋅ x − 4x ⋅ 3 − 8x−8 ⋅ 3
Simplify and combine like terms.
y = −4x^2 − 20x − 24

Answer:
A. 19
Step-by-step explanation:
2(4z -9 -7) = 166 -46
First combine like terms
2(4z -16) = 120
Divide each side by 2
2/2(4z -16) = 120/2
4z-16=60
Add 16 to each side
4z-16+16 = 60+16
4z = 76
Divide each side by 4
4z/4 = 76/4
z = 19
