Question

find the nature of root of the following quadratic equation 2 X square + 5 x + 5 is equal to zero​

Answer 1

Answer:

2x²+5x+5 = 0

D = b²-4ac

here b=5

a=2,c=5

so

D = 25-40

=> -15

so roots will be imaginary

Answer 2

Answer: Imaginary or complex numbers

Step-by-step explanation:

We know that root, x =[ -b ± $\sqrt({b^{2} } - 4ac)$]/2a for the equation a$x^{2}$ + bx + c = 0. For the given equation, $b^{2}$-$4ac$ < 0 means D<0.

So, the root will be imaginary or complex in nature.
