Can someone me out here number 4 plz

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

Step-by-step explanation:

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 4 × - 3 = - 12, sum = + 4

The factors are + 6 and - 2

Split the middle term using these factors

4x² + 6x - 2x - 3 ( factor the first/second and third/fourth terms )

= 2x(2x + 3) - 1(2x + 3) ← factor out (2x + 3)

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