Solve y=10x^3 + 5.5x^2 - 58.50x + 45.00

x ∈ {-3, 1.2, 1.25}

Step-by-step explanation:

"Solve" is non-specific as to the solution required. We assume you want the x-intercepts.

A graph shows the zeros to be ...

x = - 3 x = 1.2 x = 1.25

The equation can be factored as ...

y = (1/2) (x + 3) (4x - 5) (5x - 6)

X = - 3

X = 1.2

X = 1.25
