Question

please answer my question​

Answer 1

Answer:

True

Step-by-step explanation:

D = b² - 4ac = 7² - 4(3)(8) = 49 - 96 = -47

D < 0, so this equation has no real roots.

Answer 2

Answer

the given equation is 3x^2+7x+8=0 which is a quadratic equation.

Nature of roots of a quadratic equation of the form ax^2+bx+c=0 is determined on the basis of discriminant D which is equal to (b^2-4ac)

in this case

a= 3, b= 7, c= 8

D = (b^2-4ac)

= (7^2 - 4*3*8)

= 49 - 96

= -47

since D < 0, the quadratic equation has no roots in real numbers.
