The American title company yearly sale summarizes as 2Y+4x^2=6x+5, what is X,Y intercept, also graph the line?
Re-write equation in standard form:
y = -2x^2 + 3x + 5/2
The x intercepts are the zeroes, so
-2x^2 + 3x + 5/2 = 0
2x^2 - 3x - 5/2 = 0
Use quadratic formula to solve:
x = 2.096
x = -0.596
The y intercept is:
y = -2(0)^2 + 3(0) + 5/2
y = 2.5
Here's the graph:
Can you show me how you solved it with the quadratic formula?
So my x would be 2.096? right?
sure, the quadratic formula is
[-b +/- sqrt(b^2 - 4ac)] / 2a
in this case a = 2, b = -3, and c = -2.5
just plug in those values and you'll get the number I got.
