Question

30x2+30-16x=0 solve
​

Answer 1

Explanation:

30*2+30-16x = 0

60+30-16x = 0

90 -16x = 0

16x = 90

x = 90/16

Answer 2

Answer:

30x2+30-16x=0

  30x2-16x+30=0        (Rewritting it)

  It is a quadratic equation.

  a=30, b=-16, c=30

  D=b2-4ac

     =(-16)^2-4x30x30

     =256-3600

     =-3344

Since discriminant is less than zero (i.e. negative), the given equation will not have real roots.
