Question

if P(x) 2x³-3x²+7x-8 then P(2)​

Answer 1

16-12+14-8
10 answer
This is the answer

Answer 2

SOLUTION

GIVEN

$\sf{P(x) = 2 {x}^{3} - 3 {x}^{2} + 7x - 8 }$

TO DETERMINE

The value of P(2)

EVALUATION

Here it is given that

$\sf{P(x) = 2 {x}^{3} - 3 {x}^{2} + 7x - 8 }$

Putting x = 2 in both sides we get

$\sf{P(2) = 2 \times {(2)}^{3} - 3 \times {(2)}^{2} + 7 \times 2- 8 }$

$\sf{ \implies \: P(2) = 2 \times 8 - 3 \times 4+ 7 \times 2- 8 }$

$\sf{ \implies \: P(2) = 16 - 12+ 14- 8 }$

$\sf{ \implies \: P(2) = 4+ 6 }$

$\sf{ \implies \: P(2) = 10 }$

FINAL ANSWER

P(2) = 10
