समाधान

निर्धारित करना है

x(x+3) - 6 = 12 में x का मान

उत्तर

दिया हुआ है

 \sf{x(x + 3) - 6 = 12}

 \sf{x(x + 3) - 6 = 12}

 \sf{ \implies \:  {x}^{2} + 3x  - 6  - 12 = 0}

 \sf{ \implies \:  {x}^{2} + 3x  - 18 = 0}

 \sf{ \implies \:  {x}^{2} + 6x - 3x  - 18 = 0}

 \sf{ \implies \:x(x + 6) - 3(x + 6) = 0}

 \sf{ \implies \:(x + 6) (x  - 3) = 0}

 \sf{ \therefore \:  \: either  \: (x + 6) = 0 \:  \: or \:  \:  (x  - 3) = 0 }

 \sf{ (x + 6) = 0  \:   \:  \:  gives \:  \: x =  - 6}

 \sf{ (x  - 3) = 0  \:   \:  \:  gives \:  \: x =  3}

∴ x का मान = - 6 , 3

आवश्यक उत्तर

x का मान = - 6 , 3
