If x2+15x+50=ax2+bx+c=0. Which of the following statement is not true?

A.

x = -5

B.

x = 10

C.

x + 10 = 0

D.

bc = 750

Correct answer is B

x2+15x+50=0

x2+5x+10x+50=0

x(x+5)+10(x+5)=0

(x+5)(x+10)=0

x + 5 = 0 or x + 10 = 0.

Comparing x2+15x+50 with ax2+bx+c, b = 15 and c = 50.

bc = 750.
