Question

write the following quardeatic equation in standardform
(x-5) (x+4)
please give me ans​

Answer 1

$\huge\red{\underline{ \underline{Answer :}}}$

$\bf{(x - 5)(x + 4)}$

$\bf{x(x + 4) - 5(x + 4)}$

$\bf{ {x}^{2} + 4x - 5x - 20}$

$\bf{ {x}^{2} - 1x - 20}$

$\large \boxed{ \bf{ {x}^{2} - x - 20}}$

NOTE :

$\tt{The \: \: standard \: \: form \: \: of \: \: a \: \: quadratic \: \: equation \: \: is \: : \: \: a {x}^{2} } + bx + c$

$\tt{where \: \: a \: , \: b \: \: and \: \: c \: \: are \: \: real \: \: numbers \: \: and \: \: a \: ≠ \: 0.}$
