Answer:

2 (2x – 5) (x – 3)

Step-by-step explanation:

4x² – 22x + 30

First, factor out a 2:

2 (2x² – 11x + 15)

Use AC method to factor.

2 × 15 = 30

Factors of 30 that add up to -11 are -5 and -6.

Divide by a and reduce: -5/2, -6/2 = -3/1

The factors are 2x – 5 and x – 3.

2 (2x – 5) (x – 3)

Answer:

Lets assume a polynomial

Here GCF is 5z

all terms are divisible by 5z. so greatest common factor is 5z

One form of polynomial is

We factor the polynomial further

Other form of polynomial is

 and  are the two forms of polynomial

First form   is created by taking out GCF 5z

<h2>SEcond form   is created by factoring x^2 + 5x + 6</h2><h2></h2><h2></h2><h2></h2><h2>hope this help u !!!</h2><h2></h2>
