:

Equation at the end of step 1

(2x2 - 11x) - 63

STEP

2

:

Trying to factor by splitting the middle term

2.1 Factoring 2x2-11x-63

The first term is, 2x2 its coefficient is 2 .

The middle term is, -11x its coefficient is -11 .

The last term, "the constant", is -63

Step-1 : Multiply the coefficient of the first term by the constant 2 • -63 = -126

Step-2 : Find two factors of -126 whose sum equals the coefficient of the middle term, which is -11 .

-126 + 1 = -125

-63 + 2 = -61

-42 + 3 = -39

-21 + 6 = -15

-18 + 7 = -11 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -18 and 7

2x2 - 18x + 7x - 63

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

2x • (x-9)

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

7 • (x-9)

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

(2x+7) • (x-9)

Which is the desired factorization

Final result :

(x - 9) • (2x + 7)
