Factorization of sin²θ + sin²θ cos²θ gives us; 2sin²θ - sin⁴θ
We want to simplify;
sin²θ + sin²θ cos²θ
Let us factorize out sin²θ to get;
sin²θ(1 + cos²θ)
Now, we know that cos²θ = 1 - sin²θ
Thus;
sin²θ(1 + cos²θ) = sin²θ(1 + 1 - sin²θ)
⇒ sin²θ(2 - sin²θ)
⇒ 2sin²θ - sin⁴θ

Answer:
Step-by-step explanation:
x=16
12 = x - 4
+4 +4
By adding 4 to both sides it cancels out the -4 leaving the x alone and makes x=16
