Use the discriminant of the following quadratic equation to state the number and type of solutions x^2+4x=2x-7 a) 1 real solution b) 2 complex solutions c) 2 real solutions d) 1 complex solution

 Option b

Given a quadratic equation of the form

Let us write this in standard form of the type

Now this equation is in std form with a =1,b=2 and c =7

Discriminant =

Since discriminant is negative we find that there are two distinct complex solutions for this quadratic equation.

So Option b is right.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
