Answer 2

$\large\boxed{\textsf{\textbf{\pink{Question\::-}}}}$

${x}^{3} + 4x - 3 \: \: \: by \: \: (x + 5)$

$\large\boxed{\textsf{\textbf{\pink{Answer\::-}}}}$

you can divide by long division . If you do not like it , put :

$x + 5 = t \: ⟹ \: x = t - 5$

${x}^{3} + 4x - 3 = (t - 5) {}^{3} + 4(t - 5) - 3 = t {}^{3} - 15t {}^{2} + 75t - 125 + 4t - 20 - 3 = {t}^{3} - 15t {}^{2} + 79t - 148$

Division by t yields :

Quotient

$= {t}^{2} - 15t + 79 = (x + 5) {}^{2} - 15(x + 5) + 79 = {x}^{2} - 5x - 29$

Remainder

$= - 148$
