Relationship(38) If (x - 2) is a factor x? + 9x² + bx + 16 and b = 4a

1.	Relationship(38) If (x - 2) is a factor x? + 9x² + bx + 16 and b = 4a then find value of a and b.
Answer» Answer: a = -6.5 b = -26 Step-by-step explanation: 9x²+bx+16 X-2 is factor so x = 2 9(2)² + b(2) + 16 = 0 9(4) + 2B + 16 = 0 36 + 16 + 2b = 0 52 + 2b = 0 2b = - 52 b = -52/2 b = - 26 b = 4a -26 = 4a -26/4\\ = a a = - 6.5

Answer»

Answer:

a = -6.5

b = -26

Step-by-step explanation:

9x²+bx+16 X-2 is factor so x = 2

9(2)² + b(2) + 16 = 0

9(4) + 2B + 16 = 0

36 + 16 + 2b = 0

52 + 2b = 0

2b = - 52

b = -52/2

b = - 26

b = 4a

-26 = 4a

-26/4\\ = a

a = - 6.5
