Question

Simplify
i) (4 - 5p + 6p2 - 8p3) - (6p3 - 7p2 + 5p - 8p3)
ii) {( -13) - (-27)} + {( 25) - (-40)}​

PLEASE IT'S URGENT!!

Answer 1

Step-by-step explanation:

1. (4-5p+6p²-8p³)-(6p³-7p²+5p-8p³)

=(4-5p+6p²-8p³)-(6p³-8p³-7p²+5p)

=(4-5p+6p²-8p³)-(-2p³-7p²+5p)

=4-5p+6p²-8p³+2p³+7p²-5p

=-8p³+2p³+6p²-7p²-5p-5p+4

=6p³-p²-10p+4

2. {(-13)-(-27)}+{(25)-(-40)}

={-13+27}+{25+40}

={14}+{65}
