Question1. Factor the lollowing a) $4 \sin ^{2} \theta-\cos ^{2} \theta$

Studdy Solution
Factor the expression $4 - 5\cos^2 \theta$. Notice that it is already in a simplified form and does not factor further over the real numbers without using complex numbers or additional identities.
Thus, the expression $4 \sin^2 \theta - \cos^2 \theta$ simplifies to:
$$4 - 5\cos^2 \theta$$
