Answer:

STEP 1

Equation at the end of step 1

((0 - 3p2) + 4p) - 7

STEP 3

Pulling out like terms

3.1 Pull out like factors :

-3p2 + 4p - 7 = -1 • (3p2 - 4p + 7)

Trying to factor by splitting the middle term

3.2 Factoring 3p2 - 4p + 7

The first term is, 3p2 its coefficient is 3 .

The middle term is, -4p its coefficient is -4 .

The last term, "the constant", is +7

Step-1 : Multiply the coefficient of the first term by the constant 3 • 7 = 21

Step-2 : Find two factors of 21 whose sum equals the coefficient of the middle term, which is -4 .

-21 + -1 = -22

-7 + -3 = -10

-3 + -7 = -10

-1 + -21 = -22

1 + 21 = 22

3 + 7 = 10

7 + 3 = 10

21 + 1 = 22

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result

-3p2 + 4p - 7

Answer:

Step-by-step explanation:

-3p²+4p-7

=-3p²+(7-3)p-7

=-3p²+7p-3p-7

=p(3p+7)-1(3p+7)

=(p-1)(3p+7)
