Question

if p(x)=3x²+4x-20 then p(-3)is​

Answer 1

Answer:

P(-3) =3(-3)² +4(-3) - 20

P(-3)=27 - 12 - 20

P(-3)=27-32

P(-3)=-5

Answer 2

Answer:

$given \: p(x) = 3 {x}^{2} + 4x - 20 \: and \: p( - 3) \\ p( -3 ) = 3( - 3)^{2} + 4( - 3) - 20 \\ = 3 \times 9 + 4( - 3) - 20 \\ = 27 - 12 - 20 \\ = 27 - 32 \\ = - 5$
