-4*(7v^2+2v+9)
Step by Step Solution
Step 1 :
Equation at the end of step 1 :
((0 - (22•7v2)) - 8v) - 36
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
-28v2 - 8v - 36 = -4 • (7v2 + 2v + 9)
Trying to factor by splitting the middle term
3.2 Factoring 7v2 + 2v + 9
The first term is, 7v2 its coefficient is 7 .
The middle term is, +2v its coefficient is 2 .
The last term, "the constant", is +9
Step-1 : Multiply the coefficient of the first term by the constant 7 • 9 = 63
Step-2 : Find two factors of 63 whose sum equals the coefficient of the middle term, which is 2 .
| -63 | + | -1 | = | -64 | ||
| -21 | + | -3 | = | -24 | ||
| -9 | + | -7 | = | -16 | ||
| -7 | + | -9 | = | -16 | ||
| -3 | + | -21 | = | -24 | ||
| -1 | + | -63 | = | -64 | ||
| 1 | + | 63 | = | 64 | ||
| 3 | + | 21 | = | 24 | ||
| 7 | + | 9 | = | 16 | ||
| 9 | + | 7 | = | 16 | ||
| 21 | + | 3 | = | 24 | ||
| 63 | + | 1 | = | 64 |
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
-4 • (7v2 + 2v + 9)
