Question

divide x²-10× +21 by (x-7)

plz answer correctly ​

Answer 1

Answer:

= x2-10x +21 ÷ x-7

= x2-10x ÷x +21 -7

= x2-10x + 14

Answer 2

$\star \; {\underline{\boxed{\pmb{\green{\frak{ \; Given \; :- }}}}}}$

• P(x) = x² - 10x + 21
• g(x) = (x - 7)

$\\ \qquad{\rule{200pt}{2pt}}$

$\maltese$ Solving the Division :

$\\ \begin{gathered} \qquad \; \longrightarrow \; \; \sf { \bigg( {x}^{2} - 10x + 21 \bigg) \div \bigg( x - 7 \bigg) } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \longrightarrow \; \; {\underline{\boxed{\pmb{\sf{ x - 3 }}}}} {\pink{\bigstar}} \\ \\ \\ \end{gathered}$

$\therefore \;$ The Required answer is x - 3 .
