Solution - Simplification or other simple results
Step by Step Solution
Step 1 :
Equation at the end of step 1 :
((2•3x2) - 13x) + 6
Step 2 :
Trying to factor by splitting the middle term
2.1 Factoring 6x2-13x+6
The first term is, 6x2 its coefficient is 6 .
The middle term is, -13x its coefficient is -13 .
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 -13 .
-36 | + | -1 | = | -37 | ||
-18 | + | -2 | = | -20 | ||
-12 | + | -3 | = | -15 | ||
-9 | + | -4 | = | -13 | That's it |
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -9 and -4
6x2 - 9x - 4x - 6
Step-4 : Add up the first 2 terms, pulling out like factors :
3x • (2x-3)
Add up the last 2 terms, pulling out common factors :
2 • (2x-3)
Step-5 : Add up the four terms of step 4 :
(3x-2) • (2x-3)
Which is the desired factorization
Final result :
(2x - 3) • (3x - 2)
