Let for

a, a_1 \neq 0, a \neq a_1

f(x)=a x^2+b x+\mathrm{c}, g(x)=a_1 x^2+b_1 x+c_1

and

p(x)=f(x)-g(x)

. If

p(x)=0

only for

x=-1

and

p(-2)=2

, then the value of

p(2)

View answer and explanation

Correct option: D

Option D (18) is correct because the given conditions allow us to express p(x) as k(x+1)², solve for k using p(-2)=2, and then evaluate p(2).
