IDK your SOL sorry
SOL means sorry out of luck
Answer:
P(- 4, - 8 )
Step-by-step explanation:
The abscissa is the x- coordinate and the ordinate is the y- coordinate.
Here b = 2a , thus
a + 2a = - 12
3a = - 12 ( divide both sides by 3 )
a = - 4
and b = 2a = 2 × - 4 = - 8
P(- 4, - 8 )
x = -16 or x = 5
Solution:
Given polynomial:

To find the roots of the polynomial.
Split the middle term 11x.
11x = 16x - 5x



Take the x common in first 2 terms an -5 common in next 2 terms.

Take (x + 16) common in both terms.

x + 16 = 0 or x - 5 = 0
x = -16 or x = 5
Hence x = -16 or x = 5.
