Answer 1

$\Huge{\texttt{{{\color{Magenta}{⛄A}}{\red{N}}{\purple{S}}{\pink{W}}{\blue{E}}{\green{R}}{\red{♡}}{\purple{࿐⛄}}{\color{pink}{:}}}}}$

$\tt \purple{(4x-5)(4x-1)}$

$\boxed{ \tt \red{FORMULA=(x+a)(x+b)=x² (a+b)x+ab}}$

$\tt \orange{x=4x;a=-5;b= -1}$

$\tt \orange{ \longrightarrow(4x)²+(-5+(-1))4x+(-5)(-1).}$

$\tt \orange{ \longrightarrow16x²-5-1 \times 4x-5 \times (-1)}$

$\tt \orange{ \longrightarrow16x²-24x+5.}$
