Question

in this equation , what is the value of b^2-4ac 2x^2+6x+5=0Note that the general form of a quadratic equation is ax^2+bx+c=0

Answer 1

-4

Step-by-step explanation

Given the standard form of a quadratic equation expressed as ax^2 + bx + c = 0

Comparing to the given equation 2x^2+6x+5=0

ax^2 = 2x^2

a = 2

bx = 6x

b = 6

c = 5

Get b^2 - 4ac

Substitute the values of a, b and c into b^2 - 4ac

b^2 - 4ac

= 6^2 - 4(2)(5)

= 36 - 40

= -4

Hence the value of b^2 - 4ac is -4
