A. 2x+11
B. 7x+7
C. 2x+7
D. X+1

Answer 1

Question:-

What is (2x² + 9x + 7) = (x + 1) ?

Solution:-

2x² + 9x + 7 = x + 1

2x² + 9x - x + 7 - 1 = 0

2x² + 8x + 6 = 0

2(x² + 4x + 3) = 0

x² + 4x + 3 = 0

x² + 3x + x + 3 = 0

x( x + 3) + 1(x + 3) = 0

(x + 3)(x + 1) = 0

So, option (D) x + 1 is correct. [Answer]
