Question

x² + (25-20)x-500=0​

Answer 1

x² +(25-20)x - 500 = 0

x² + 5x - 500 = 0

x² - 20x + 25x - 500 = 0

x (x - 20) + 25(x - 20= 0

(x-20)(x-25)= 0

x = 25 or 20

Answer 2

$\huge \star \; \bf \underbrace {ANSWER} \: \star$

‣ Given :

$\sf {x^{2} + (25 - 20)x - 500}$

‣ To Find :

$\textsf {The value of x}$

‣ Solution :

➡ $\sf {x^{2} + (25 - 20)x - 500}$

$\sf {= x^{2} + 25x - 20x - 500}$

$\sf {= x(x + 25) - 20(x + 25)}$

$\sf {= (x + 25) (x - 20)}$

$\implies \textsf {\underline {\underline {The value of x :}} }$

• $\sf {x + 25 = 0}$

$\rightarrow \sf {x_{1} = \fbox { - 25}}$

• $\sf {x - 20 = 0}$

$\rightarrow \sf {x_{2} = \fbox { 20} }$
