Question

If the area of the rectangle is 4x² + 4x – 3, then find its possible dimensions.
a) 2x – 3, 2x + 1 b) 2x – 1, 2x + 3
c) 3x + 1, 2x – 3 d) 3x – 1, 2x + 3

Answer 1

Answer:

b) 2x – 1, 2x + 3

Step-by-step explanation:

4x² + 4x – 3 = 0

4x² + 6x - 2x - 3 = 0

2x(2x + 3) - 1 (2x + 3) = 0

(2x + 3)(2x - 1) = 0

Therefore, b) 2x – 1, 2x + 3 is the correct option
