Answer 1

Answer :

$\implies \large -13$

Solution :

Given :

-3p²+4p+7

To Find :

Value of equation if p= -2

Let's solve,

$\sf -3p^2+4p+7 \\ \\ \implies \sf -3(-2)^2 + 4(-2) + 7 \\ \\ \implies \sf -3(4) -8 + 7 \\ \\ \implies -12 - 8 + 7 \\ \\ \implies \sf -20 + 7 \\ \\ \implies \sf -13$

Answer 2

Answer:

-13

Step-by-step explanation:

Question is -3p2 + 4p + 7

value of p is -2

so,

-3p2 + 4p + 7

=(-3)x(-2)2 + 4(-2) + 7

=(-3)x4 + (-8) + 7

=(-12) + (-8) + 7

=(-20) + 7

=(-13)
