Question

if p(x)=3x²+4x-20 then p(-3)is​

Answer 1

Answer:

-5

Step-by-step explanation:

3(-3)^2 + 4(-3) -20

27 -12 -20

-5

Answer 2

Answer:

${ \large{ \underline { \sf{Solution-\: }}}}$

$: { \implies{ \sf{p(x) = 3 {x}^{2} + 4x - 20}}}$

${ : { \implies{ \sf{p( - 3) = 3 {( - 3)}^{2} + 4( - 3) - 20 }}}}$

$: { \implies{ \sf{p( - 3) = 3(9) + ( - 12) - 20}}}$

$: { \implies{ \sf{p( - 3) = 27 - 12 - 20}}}$

$: { \implies{ \sf{p( - 3) = 27 - 32}}}$

$: { \implies{ \sf{p( - 3) = - 5}}}$

${ \therefore { \underline{ \rm{\pmb{The \: Value \: of \: p(-3) \: is \: -5}}}}}$
