Question

write the nature roots of the quadratic equation 2 x^2+5x+6=0​

Answer 1

Answer:

Step-by-step explanation:

Given,

2x^2 + 5x + 6 = 0

Here, a = 2, b = 5, c = 6

x = -b ± √b^2 - 4ac / 2a

= -5 ± √(5)^2 - 4 × 2 × 6 / 2 × 2

= -5 ± √ 25 - 48 / 4

= -5 ± √ - 23 / 4

= -5 ÷ √-23 / 4 or -5 - √-23 / 4
