Question

If p= -2 find the value of

-2p²-3p²+4p+7

Answer 1

☯GIVEN :

• p = -2

☯TO FIND :

• The value of -2p² - 3p² + 4p + 7.

➲SOLUTION :

Substituting the given value :

$\implies {\sf{ - 2p^2 - 3p^2 + 4p + 7}}$

$\implies {\sf{ - 2( - 2)^2 - 3( - 2)^2 + 4( - 2) + 7}}$

$\implies {\sf{ - 2 (4 ) - 3 (4) + 4( - 2) + 7}}$

$\implies {\sf{ - 8- 12 - 8 + 7}}$

$\implies {\sf{ - 28+ 7}}$

$\implies { \underline{ \huge{ \boxed{ \green{\bf{ - 21}}}}}}$

$\huge{ \pink{\therefore}}$ The value of -2p² - 3p² + 4p + 7 is -21.
