Question

what are the polynomial of p(x)=2x^2-x-3​

Answer 1

Answer :-

• $\sf \longrightarrow p(x) = 2x² - x - 3$

• $\sf \longrightarrow$ p(x) = 0

• $\sf \longrightarrow 0 = 2x² - x - 3$

• $\sf \longrightarrow 2x² - x - 3 = 0$

• $\sf \longrightarrow 2x² + 2x - 3x - 3 = 0$

• $\sf \longrightarrow 2x ( x + 1 ) - 3 ( x + 1 ) = 0$

• $\sf \longrightarrow ( x + 1 ) (2x - 3 ) = 0$

• $\sf \longrightarrow x + 1 = 0 \: \: \: \: \: \: \: or \: \: \: \: \: \: \: 2x - 3 = 0$

• $\sf \longrightarrow x = - 1 \: \: \: \: \: \: \: or \: \: \: \: \: \: \: 2x = 3$

$\sf \longrightarrow \underline{\underline{x = - 1}} \: \: \: \: \: \: \: or \: \: \: \: \: \: \: \underline{\underline{ x = \frac{3}{2}} }$
