Step by Step Solution
Step 1 :
Equation at the end of step 1 :
((2•3x2) - 7x) - 10
Step 2 :
Trying to factor by splitting the middle term
2.1 Factoring 6x2-7x-10
The first term is, 6x2 its coefficient is 6 .
The middle term is, -7x its coefficient is -7 .
The last term, "the constant", is -10
Step-1 : Multiply the coefficient of the first term by the constant 6 • -10 = -60
Step-2 : Find two factors of -60 whose sum equals the coefficient of the middle term, which is -7 .
| -60 | + | 1 | = | -59 | ||
| -30 | + | 2 | = | -28 | ||
| -20 | + | 3 | = | -17 | ||
| -15 | + | 4 | = | -11 | ||
| -12 | + | 5 | = | -7 | That's it |
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -12 and 5
6x2 - 12x + 5x - 10
Step-4 : Add up the first 2 terms, pulling out like factors :
6x • (x-2)
Add up the last 2 terms, pulling out common factors :
5 • (x-2)
Step-5 : Add up the four terms of step 4 :
(6x+5) • (x-2)
Which is the desired factorization
Final result :
(x - 2) • (6x + 5)
