Step by Step Solution
Step 1 :
Equation at the end of step 1 :
((2•3x2) + 7x) - 3
Step 2 :
Trying to factor by splitting the middle term
2.1 Factoring 6x2+7x-3
The first term is, 6x2 its coefficient is 6 .
The middle term is, +7x its coefficient is 7 .
The last term, "the constant", is -3
Step-1 : Multiply the coefficient of the first term by the constant 6 • -3 = -18
Step-2 : Find two factors of -18 whose sum equals the coefficient of the middle term, which is 7 .
-18 | + | 1 | = | -17 | ||
-9 | + | 2 | = | -7 | ||
-6 | + | 3 | = | -3 | ||
-3 | + | 6 | = | 3 | ||
-2 | + | 9 | = | 7 | That's it |
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -2 and 9
6x2 - 2x + 9x - 3
Step-4 : Add up the first 2 terms, pulling out like factors :
2x • (3x-1)
Add up the last 2 terms, pulling out common factors :
3 • (3x-1)
Step-5 : Add up the four terms of step 4 :
(2x+3) • (3x-1)
Which is the desired factorization
Final result :
(3x - 1) • (2x + 3)
