Answer:

he solution of the quadratic equation is x=-9 and x =2

So (a) and (f) are correct option

Explanation:

We have given the equation
2x^2+7x=14=x^2+4


x^2+7x-18=0


x^2+9x-2x-18=0


x(x+9)-2(x+9)

Now taking (x+9) common


(x+9)(x-2)=0

x = -9 and x= 2 are the roots of the equation

So the solution of the quadratic equation is x=-9 and x =2

So (a) and (f) are correct option
