Question

find the product of (p+8)(p-7)​

Answer 1

Answer:

(p+8)(p-7)

= (p*p-7p)+(8p-56)

= p²-7p+8p-56

= p²+1p-56

Answer 2

Step-by-step explanation:

find the product of (p+8)(p-7)

$\tt \: {p}^{2} - 7p +8 p - 56 \\ \\ \tt \: p}^{2} + p - 56 = 0 \\ \\ \tt \: p}^{2} + 8p - 7p - 56 = 0 \\ \\ \tt \:p(p + 8) - 7(p + 8) = 0 \\ \\ \tt \:( p - 7)(p + 8) = 0 \\ \\ \tt \red{p = 7}\\ \tt\pink{p = - 8}$
