Question

Find the value if discriminant 2y^2-5y+10=0

Answer 1

we have to discriminant is it

b^2-4ac

25-4×2×10

25-80

=55 is the answer

hope it helps

Answer 2

Here is the answer

Comparing the given Equation with ax^2 + bx + c = 0

We get,
a = 2
b = -5
c = 10

Now,

$\bf{ \triangle = {b}^{2} - 4ac}$
$\bf{ = ( - 5) {}^{2} - 4 \times 2 \times 10}$
$\bf{ = 25 - 80}$
$\bf{ = - 55}$

Thus,
The value of discriminant is -55.

Thanks!!
