B. x2 + 7x + 6 = 0
C. x2 + 7x + 12 = 0
D. x2 + 4x + 6 = 0

Answer 1

${x}^{2} + 7x + 9 = 3 \\ {x}^{2} + 7x + 9 - 3 = 0 \\ {x }^{2} + 7x + 6 = 0$
The answer should be B

Answer 2

The equation below written in the form ax2 + bx + c = 0 is Option(B) $x^{2} + 7x + 6$ .

How to simplify the given expression ?

Given expression is $x^{2} + 7x + 9 = 3$
