Question

If p (x)=x2+x+2 find p(1)+p(-1)

Answer 1

Answer:

1+1+2+1-1+2=6 is the answer.

Answer 2

$\huge\underline\mathbb{\red S\pink{O}\purple{L} \blue{UT} \orange{I}\green{ON :}}$

★ Given that,

• p(x) = x² + x + 2
• p(x) = 1
• p(x) = - 1

$\tt{1)\:p(x)\:=\:1}$

➡ (1)² + (1) + 2

➡ 1 + 1 + 2

➡ 4

$\tt{2)\:p(x)\:=\:-1}$

➡ (-1)² + (-1) + 2

➡ 1 - 1 + 2

➡ 2

$\underline{\boxed{\tt{\purple{∴Hence, \:p(1)\:=\:4\:and\:p(-1)\:=\:2}}}}$
