If x=2 and x=0 are zeroes of the polynomial 2xsquare -5xsquare +ax+b,find the values of a and b
If x=2 and x=0 are zeroes of the polynomial 2xsquare -5xsquare +ax+b,find the values of a and b
see now it is correct

p(2)=2(2)^2-5(2)^2+2a+b
8-10+2a+b
-2+2a+b
2a+b=2
p(0)=2(0)^2-5(0)^2+0a+b
0a+b=0
2a+b=2
change the sign
a-b=0
a=2
b=-2
