4.For a polynomial p(x) = -2 +3x-x²+5x³ , p(3) is _________ ​

Answer 1

$\underline{\boxed{\bold{Question}}}$

• For a polynomial p(x) = -2 + 3x - x² + 5x³ , then find p(3) = ?

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

$\underline{\boxed{\bold{Answer}}}$

Let's Start !

Here to find p(3) , we just need to substitute x = 3 in the given polynomial p(x).

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

$:\implies p(x) = -2 + 3x -x^{2} + 5 x^{3}$

$:\implies p(3) = -2 + 3(3) -(3)^{2} + 5 (3)^{3}$

$:\implies p(3) = -2 + 9 -9 + 5 (27)$

$:\implies p(3) = 5 (27) - 2$

$:\implies p(3) = 135 - 2$

$:\implies p(3) = 133$

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

$\boxed{\boxed{\bold{\therefore Value\; of\; p(3) = 133}}}$
