Question

solve it 4x^2+21x=6x-14 ?

​

Answer 1

4x²+21x = 6x -14

=> 4x²+15x +14 = 0

=> 4x²+8x+7x+14 =0

=> 4x(x+2)+7(x+2)=0

=> (4x+7)(x+2)=0

=> x = -7/4 or x = -2

Answer 2

↪4x² + 21x = 6x - 14

↪4x² + 15x + 14 = 0

↪4x² + 8x + 7x + 14 = 0

↪4x(x + 2) + 7(x + 2)= 0

↪(4x + 7)(x + 2) = 0

x = -7/4

x = - 2

, Values of x are -2 , -7/4

↪4x² + 21x = 6x - 14

↪4x² + 15x + 14 = 0

↪4x² + 8x + 7x + 14 = 0

↪4x(x + 2) + 7(x + 2)= 0

↪(4x + 7)(x + 2) = 0

x = -7/4

x = - 2

, Values of x are -2 , -7/4
