Step-by-step explanation:
Consider the given quadratic equation
This can be rewritten as,
We can solve the quadratic equation using middle term splitting method,
4x can be written as 7x-3x , we get,
Taking terms common, we get,
Thus,
Thus, we get (x-3)= 0 or (x+7)= 0
this gives x = 3 or x = -7
Thus, the solution of the quadratic equation is -7 and 3
