(a) (x + 5) (x + 4)
(b) (p – 2) (p + 1)

​

Answer 1

$\bf\red { Question: }$

$\sf\purple { (x + 5) (x + 4) }$

$\bf\red { Solution: }$

$\sf {: \implies x(x+4)+5(x+4) }$

$\sf {: \implies {x}^{2} + 4x + 5x + 20 }$

$\sf {: \implies {x}^{2} + 9x + 20 \: Ans }$

$\bf\red { Question: }$

$\sf\purple { (p-2) (p+ 1) }$

$\bf\red { Solution: }$

$\sf {: \implies p(p+1)-2(p+1) }$

$\sf {: \implies {p}^{2} + p -2p - 2 }$

$\sf {: \implies {p}^{2} -p - 2 \: Ans}$
