Question

P of x is equal to X square + 3 x square - 2 x minus 8 find the value of P of x if x is equal to 2​

Answer 1

Step-by-step explanation:

1. x=2
2. p(x) = x^2 + 3x^2 - 2x -8

p(2)=2^2 + 3(2)^-2(2)-8

= 2×4 +3×4 -4-8

=4+12-12

= 4

Answer 2

Question:

p(x) = x²+ 3x² - 2x - 8

x = 2

Step-by-step explanation:

Substituting x in the equation

p(2) = 2²+ 3(2)² - 2(2) - 8

p(2) = 4 + 3(4) - 4 - 8

p(2) = 4 + 12 - 12

∴ p(x) = 4
