Question

Solve.
1. x^2+7x-44=0​

Answer 1

By splitting middleterm:-

multiply first term and last term[(x^2*(-44)]=(-44x^2) then split the the product(-44x^2) in such a way that it give middle term by adding or subtracting it (11x-4x)

=>x^2+11x-4x-44=0

Now,taking common we get:

=>x(x+11)-4(x+11)=0

=>(x-4)(x+11)=0

=>x=4 and (-11)
