Question :

Divide:

✒ 5x³-15x²+25x by 5x

To find :

The reminder =?

Solution :

$\\ \implies \large \sf \: \frac{ \green{5 {x}^{3} - 15 {x}^{2} + 25x }}{ \pink{5x} }$

$\\ \implies \large \sf \: \frac{ \green{5 {x}^{3}} }{ \pink{5x}} - \frac{ \green{15 {x}^{2} }} { \pink{5x}} + \frac{ \green{25x}}{ \pink{5x} }$

$\\ \implies \large \sf \: \cancel \frac{ \green{5 {x}^{3} }}{ \red{5x}} - \cancel \green{\frac{15 {x}^{2} }{ \red{5x}}} - \cancel \frac{ \green{25x}}{ \red{5x} }$

$\\ \implies \large \sf \: \blue {{x}^{2} - 3x + 5} \: \: \: \: ....remainder$

$\pink \bigstar \large \red{ \boxed{ \underline{ \bf{ \:the \: answer \: will \: be \: {x}^{2} - 3x - 5}}}}$
