Question

Q4.
If (x+5) a factor of x' + 2x² - 14x +9?​

Answer 1

Answer:

Given :

• x + 5 is a factor of p(x)

Solution :

• x + 5 = 0
• x = (-5)

x' + 2x² - 14x + 9

• 2x² - 13x + 9
• 2(-5)² - 13(-5) + 9
• 2(25) + 65 + 9
• 50 + 65 + 9
• 124

Answer : 124

Answer 2

Answer:

Solution :

• x + 5 = 0
• x = (-5)

x' + 2x² - 14x + 9

• 2x² - 13x + 9
• 2(-5)² - 13(-5) + 9
• 50 + 65 + 9
• 124

Answer = 124
