The quadratic has one root with multiplicity 2 if the discriminant is 0, which is

(That is, for a quadratic
, the discriminant is
.)
Set the discriminant equal to 0 and solve for
:





Answer:
x=-6
Step-by-step explanation:
2x+y=-4
5x+3y=-6
solve :
multiply first equation by 3
6x+3y=-12
5x+3y=-6
subtract the two equations : 6x+3y-5x-3y=-12-(-6)
x=-12+6
x=-6

Step-by-step explanation:</h2>
The function f(x) is given by:

and the function g(x) is given by:

Now, we are asked to find the solution of the equation:

i.e. we have to find the value of x such that both the functions are equal i.e.

Now, on solving the equation using the quadratic formula i.e. the solution of the equation:

is given by:

Here we have:

Hence, the solution is given by:
