Answer: (p - 1) • (5p + 3)

Step-by-step explanation: Changes made to your input should not affect the solution:

(1): "p2" was replaced by "p^2".

STEP

1

:

Equation at the end of step 1

(5p2 - 2p) - 3

STEP

2

:

Trying to factor by splitting the middle term

2.1 Factoring 5p2-2p-3

The first term is, 5p2 its coefficient is 5 .

The middle term is, -2p its coefficient is -2 .

The last term, "the constant", is -3

Step-1 : Multiply the coefficient of the first term by the constant 5 • -3 = -15

Step-2 : Find two factors of -15 whose sum equals the coefficient of the middle term, which is -2 .

-15 + 1 = -14

-5 + 3 = -2 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -5 and 3

5p2 - 5p + 3p - 3

Step-4 : Add up the first 2 terms, pulling out like factors :

5p • (p-1)

Add up the last 2 terms, pulling out common factors :

3 • (p-1)

Step-5 : Add up the four terms of step 4 :

(5p+3) • (p-1)

Which is the desired factorization
