$\huge\underline\frak{\fbox{Question :-}}$

एक धनात्मक पूर्णांक का 5 गुना, उस संख्या के वर्ग के दो गुने से 3 कम है| वह संख्या क्या होगी?

$\huge\underline\frak{\fbox{AnSwEr :-}}$

$\longrightarrow$ x = 3

Step by step explanation : $\text{[math]}$

हल:- माना वह धनात्मक संख्या x है।

तब

$\longrightarrow$ 2x² = 5X + 3

$\longrightarrow$ 2x² - 5x - 3 = 0

$\longrightarrow$ 2x² - 6x + x - 3 = 0

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

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

$\longrightarrow$ x = 3
