Step by Step Solution
Step 1 :
Equation at the end of step 1 :
((2•3x2) + 5x) - 6
Step 2 :
Trying to factor by splitting the middle term
2.1 Factoring 6x2+5x-6
The first term is, 6x2 its coefficient is 6 .
The middle term is, +5x its coefficient is 5 .
The last term, "the constant", is -6
Step-1 : Multiply the coefficient of the first term by the constant 6 • -6 = -36
Step-2 : Find two factors of -36 whose sum equals the coefficient of the middle term, which is 5 .
-36 | + | 1 | = | -35 | ||
-18 | + | 2 | = | -16 | ||
-12 | + | 3 | = | -9 | ||
-9 | + | 4 | = | -5 | ||
-6 | + | 6 | = | 0 | ||
-4 | + | 9 | = | 5 | That's it |
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -4 and 9
6x2 - 4x + 9x - 6
Step-4 : Add up the first 2 terms, pulling out like factors :
2x • (3x-2)
Add up the last 2 terms, pulling out common factors :
3 • (3x-2)
Step-5 : Add up the four terms of step 4 :
(2x+3) • (3x-2)
Which is the desired factorization
Final result :
(3x - 2) • (2x + 3)
