Question

Hello

Factorise :

${p}^{2} + p - 56$
​

Answer 1

Given Equation is p^2 + p - 56.

=> p2 - 7p + 8p - 56

=> p(p - 7) + 8(p - 7)

=> (p - 7)(p + 8).

Its zeroes are:

p = 7, -8.

Hope this helps!

Answer 2

Answer:

${p}^{2} + p - 56$

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