Question

x(x+3)-6=12 mein, x ka maan Kya hoga ?​

Answer 1

Answer:

x=-6 or x=3

Step-by-step explanation:

x(x+3)-6=12

x^2+3x-6-12=0

x^2+3x-18=0

x^2+6x-3x-18=0

x(x+6)-3(x+6)=0

(x+6) (x-3)=0

x+6=0 or x-3=0

x=-6 or x=3

Answer 2

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
