Question

factorize 15+p(7-2p)

Answer 1

15+p(7-2p)
=> 15+7p-2p²
=> -2p²+7p+15
=> -2p²+10p-3p+15
=> -2p(p-5)-3(p-5)
=> (p-5)(-2p-3)

Answer 2

Hey mate

Here is ur answer

$15 + p(7 - 2p) \\ 15 + 7p { - 2p}^{2} \\ {2p}^{2} - 7p - 15 \\ {2p}^{2} - (10 - 3)p - 15 \\ {2p}^{2} - 10p + 3p - 15 \\ 2p(p - 5) + 3(p - 5) \\ (2p + 3) \: (p - 5) \\ p = - 3 \div 2 \: \: \: \: \: p = 5$
