20=n/5+10 minus 10 both sides 10=n/5 times 5 both sides 50=n
2. hmm expand p(x)=2x^2+5x+3-3x-3n p(x)=2x^2+2x+3-3n it looks like the coefients of the x terms are divisble by 2 because if we have p(x)=2(something) the p(x) is divisible by 2
therefor that factor is 2 or -2 find what value of n works so 3-3n=a multipule of 2 we are given -3,-2,0,2 try each 3-3(-3)=3+9=12, that's divisble by 2 3-3(-2)=3+6=9, that's not divisible by 2 3-3(0)=3, that's not divisble by 2 3-3(2)=3-6=3, that's not divisble by 2
