1/d-2+7/2d2-d-6 simplify this question
Answers
Step-by-step explanation:
Factoring 2d2-7d+6
The first term is, 2d2 its coefficient is 2 .
The middle term is, -7d its coefficient is -7 .
The last term, "the constant", is +6
Step-1 : Multiply the coefficient of the first term by the constant 2 • 6 = 12
Step-2 : Find two factors of 12 whose sum equals the coefficient of the middle term, which is -7 .
-12 + -1 = -13
-6 + -2 = -8
-4 + -3 = -7 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -4 and -3
2d2 - 4d - 3d - 6
Step-4 : Add up the first 2 terms, pulling out like factors :
2d • (d-2)
Add up the last 2 terms, pulling out common factors :
3 • (d-2)
Step-5 : Add up the four terms of step 4 :
(2d-3) • (d-2)
Which is the desired factorization
