How would you solve 2x^2 -4x -3 = 0

ANSWER

EXPLANATION

The given quadratic equation is

This function is of the form:

This implies that:

a=2, b=-4 and c=-3.

We can solve this equation using the quadratic formula:

We substitute the values into the quadratic formula to obtain;

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
