Jenna constructs the model to represent 3x2 + 11x – 4. what factors does jenna need to model for the sides? (3x + 1) and (x – 4) (3x – 1) and (x + 4) (3x – 2) and (x + 2) (3x + 2) and (x – 2)

(3x - 1) and (x + 4)

Step-by-step explanation:

Given

3x² + 11x - 4

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 = 3 × - 4 = - 12 and sum = + 11

The factors are + 12 and - 1

Use these factors to split the x- term

3x² + 12x - x - 4 ( factor the first/second and third/fourth terms )

= 3x(x + 4) - 1(x + 4) ← factor out (x + 4) from each term

= (x + 4)(3x - 1) ← factors required
