Answer:
Step-by-step explanation:
We are required to represent the expression given in the standard form to the quadratic form
Given
let us square the given expression
f(x)=(x+3)(x+3)
open brackets
sum the similar terms
Best to draw out a factor tree.
tan(θ) = 0, 0.577, -0.577
3tan³(θ) - tan(θ) = 0
tan(θ)(3tan²(θ) - 1) = 0
tan(θ) = 0
tan²(θ) = ⅓ tan(θ) = +/- sqrt(⅓)
tan(θ) = 0, sqrt(⅓), -sqrt(⅓)
To find θ values, domain is required
