If A = –2p + 7 and B = p2 + 3p – 5, find an expression that equals A – 3B in
standard form.

-3p^2 - 11p + 22

Step-by-step explanation:

A - 3B becomes (-2p + 7) - 3*(p^2 + 3p - 5).

Perform the indicated multiplication, obtaining:

                            (-2p + 7) - 3p^2 - 9p + 15, and then:

                              -2p + 7 - 3p^2 - 9p + 15, or (combining like terms):

                                 -3p^2 - 11p + 22

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.
