4x² + 4x – 3 = ?

We have,

4x² + 4x – 3

= 4x² – 2x + 6x – 3

= 2x (2x – 1) + 3 (2x – 1)

= (2x – 1) (2x + 3)

Hence, option D is correct

When p (x) = 4x³ - 12x² + 11x – 5 is divided by (2x – 1), the remainder is

(x +1) is a factor of the polynomial:

6x² + 17x + 5

x² - 4x – 21 = ?

4x2 + 4x – 3 = ?
