Step by Step Solution
Step 1 :
Trying to factor by splitting the middle term
1.1 Factoring x2-70x-6000
The first term is, x2 its coefficient is 1 .
The middle term is, -70x its coefficient is -70 .
The last term, "the constant", is -6000
Step-1 : Multiply the coefficient of the first term by the constant 1 • -6000 = -6000
Step-2 : Find two factors of -6000 whose sum equals the coefficient of the middle term, which is -70 .
| -6000 | + | 1 | = | -5999 | ||
| -3000 | + | 2 | = | -2998 | ||
| -2000 | + | 3 | = | -1997 | ||
| -1500 | + | 4 | = | -1496 | ||
| -1200 | + | 5 | = | -1195 | ||
| -1000 | + | 6 | = | -994 | ||
| -750 | + | 8 | = | -742 | ||
| -600 | + | 10 | = | -590 | ||
| -500 | + | 12 | = | -488 | ||
| -400 | + | 15 | = | -385 | ||
| -375 | + | 16 | = | -359 | ||
| -300 | + | 20 | = | -280 | ||
| -250 | + | 24 | = | -226 | ||
| -240 | + | 25 | = | -215 | ||
| -200 | + | 30 | = | -170 | ||
| -150 | + | 40 | = | -110 | ||
| -125 | + | 48 | = | -77 | ||
| -120 | + | 50 | = | -70 | That's it |
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -120 and 50
x2 - 120x + 50x - 6000
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-120)
Add up the last 2 terms, pulling out common factors :
50 • (x-120)
Step-5 : Add up the four terms of step 4 :
(x+50) • (x-120)
Which is the desired factorization
Final result :
(x + 50) • (x - 120)
