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
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.
