2x+7y=4
+(-2x-8y=-2)
------------------
0x-y=2
-y=2 (this is the result of adding the two equations)
But...
y=-2
2x+7(-2)=4
x=9
After factoring we get
Step-by-step explanation:
We need to factorize the polynomial:
Factorization is done by breaking the middle term such that the sum is equal to the middle value of polynomial and product is equal to product of first and last term in the polynomial.
So, Factorizing:
So, After factoring we get
