1. Factorize:

a) 7(x+y)² + 48(x+y) - 7

b) 5 - 20x²

c) 2xy² - 22xy + 48x

I tried a lot to solve these equations, can't work it out!! Here are some of the solutions i got!! for (a):

=7(x²+2xy+y²) + 48 (x+y) - 7

=7x²+14xy+7y²+48x+48y - 7

(cant work it out any further)

for (b):

(√5)² - (2√5)²

(√5+2√5) (√5+2√5) (is it correct??!!)

i cant even think of away to work out the third one!!!

( i know this is maths but pls help me out!!)
