Answer:

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

So (a) and (f) are correct option

Step-by-step explanation:

We have given the equation [tex]2x^2+7x=14=x^2+4[/tex]

[tex]x^2+7x-18=0[/tex]

[tex]x^2+9x-2x-18=0[/tex]

[tex]x(x+9)-2(x+9)[/tex]

Now taking (x+9) common

[tex](x+9)(x-2)=0[/tex]

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
