Factorise 12+7y-6y^2
Answers
Answer:
HERE IS YOUR ANSWER!!!
Step-by-step explanation:
(2•3y2) - 7y) - 12
STEP
2
:
Trying to factor by splitting the middle term
2.1 Factoring 6y2-7y-12
The first term is, 6y2 its coefficient is 6 .
The middle term is, -7y its coefficient is -7 .
The last term, "the constant", is -12
Step-1 : Multiply the coefficient of the first term by the constant 6 • -12 = -72
Step-2 : Find two factors of -72 whose sum equals the coefficient of the middle term, which is -7 .
-72 + 1 = -71
-36 + 2 = -34
-24 + 3 = -21
-18 + 4 = -14
-12 + 6 = -6
-9 + 8 = -1
-8 + 9 = 1
-6 + 12 = 6
-4 + 18 = 14
-3 + 24 = 21
-2 + 36 = 34
-1 + 72 = 71
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
6y2 - 7y - 12
