Question

)
P(x) = 4x²-5x
-3 then
P(-2)​

Answer 1

Answer:

23

Step-by-step explanation:

P(-2)=4x^2-5x-3

= 4(-2)^2-5(-2)-3

=4(4)+10-3

=16+10-3

= 26-3

=23

Answer 2

FINAL ANSWER:-

23

GIVEN:-

$P(x) = 4x^{2}-5x-3\\x=-2$

TO FIND:-

value of quadratic polynomial

SOLUTION:-

in the polynomial 4x²-5x -3  ;  x=-2

so , put x in eq we get

$P(x) = 4x^{2}-5x-3\\P(-2) = 4x^{2}-5x-3\\=4(-2)^{2}-5(-2)-3\\=4(4)+10-3\\=16+7\\=23$
