cutegirl2213: any other mistake

23415: i think no..wait...let me check again

23415: is the answer means values of x 4,-1?

cutegirl2213: no

cutegirl2213: here we have to factorise

cutegirl2213: its correct ans is (2a+b-1)(2a+b+4)

23415: you have made a mistake in sign...go through ur answer..hope u will find it!

cutegirl2213: i didn't found it

23415: (2a+b)^2-6a-3b-4 =(2a+b)^2-(6a+3b)-4=(2a+b)^2-3(2a+b)-4

23415: now we can write let (2a+b)=x
