What is the discriminant of the quadratic equation 0 = 2x2 + 3x – 5?

Answer 1

Given:-

• Quadratic Equation → 2x²+3x-5 = 0.

To Find:-

• Discriminate of the QE.

Solution:-

2x²+3x-5 = 0 is in the form of ax²+bx+c = 0

$\boxed{\pink{\sf{\star\;D = b²-4ac}}}$

a = 2, b = 3 & c = -5

$( {3})^{2} - 4(2)( - 5) \\ 9 - 4( - 10) \\ 9 + 40 \\ 49$

• Discriminate = $\red{\bold{49}}$
