and questions no. 6.. ka amswer is x²+x-20
and answer no. 8_ x=1/2,5/2
answer mujhe bhi pta h aap explain krke btao
ohh.
wait
no.6. if alplh(a) and bita(b) then a= -5 or b=1 so.. a+b = -1. and ab= -20 now as we know that for p(x) polynomial =x²-(a+b)+ab now put the value.. then it become x²+x-20
no.8 ..... now 4x²-12x+5 so.. we esplit the middle term then it like 4x²-10x-2x+5 now take common in bith term so 2x(2x-1)-5(2x-1) and take commen in one (2x-5)(2x-1) now it solve so.. x=5/2and 1/2
for questions no. 7 is not clear view
