Question

Q. Find the value of discriminant
4y2 – 3y = -7​

Answer 1

Formula to find discriminant part is b²-4ac=0

4y²-3y+7=0

Here a=4;b=-3 and c=7

b²-4ac= (-3)²-4×4×7=0

=9-112=0

=-121=0

Answer 2

Answer:

we know,

discriminant=b2-4ac

then we have.

a=4 b=-3 c=7

now,

b2-4ac=(-3)×2-4×4×7=9-112=-103
