Re: Algebra

abhimath,
Welcome to the forum!
You have come to the right place, you can get lot of help, HERE, in this forum.
Post your problems here.
To begin with, I can help you a little with factorization in Algebra.
Examples:-

Factorize

(a) x²+3x+2
x²+3x+2 = x²+x+2x+2 = x(x+1)+2(x+1) = (x=2)(x+1)

(b) x²-11x+30
x²-11x+30 = x²-6x-5x+30 = x(x-6) - 5(x-6) = (x-5)(x-6)

(c) x²-16
x²-16 => x² = 16 => x = ±4 =>
x²-16 = (x+4)(x-4)
