Question

Find the value of P(x)
=3x³ -4x² + 7x -5 where
x=3 and x = -3​

plzzz answer this question

Answer 1

If X = 3

= 3x³ -4x² + 7x -5

= 3(3)³ - 4(3)² + 7(3) - 5

= 81 - 36 + 21 - 5

= 102 - 41

= 61

If X = -3

= 3x³ -4x² + 7x -5

= 3(-3)³ - 4(-3)² + 7(-3) - 5

= - 81 - 36 - 21 - 5

= - 143
