To simplify this expression we first need to apply the distributive property of the product. This means that we need to multiply the number outside of the parenthesis by each term of the sum inside the parenthesis. This is done below:
The simplified expression is "-20+12w".
Answer:
turning point: (-3 , -16)
Step-by-step explanation:
y = x² + ax + b pass(0,-7)(7,0)
(0)² + 0*a + b = -7 b= -7
(7)² + 7*a - 7 = 0 7a = 42 a = 6
y = x² + ax + b = y = x² + 6x - 7 = (x+3)² - 16
(h,k): vertex equation: y = a(x-h)² + k
h = -3 k=-16
