$\left(\cos\left(3x\right)\left(12+6\cos\left(3x\right)+\cos\left(3x\right)^2\right)\right)^2$
Learn how to solve factor problems step by step online. Factor the expression (12cos(3x)+6cos(3x)^2cos(3x)^3)^2. Factor the polynomial \left(12\cos\left(3x\right)+6\cos\left(3x\right)^2+\cos\left(3x\right)^3\right) by it's greatest common factor (GCF): \cos\left(3x\right). The power of a product is equal to the product of it's factors raised to the same power. Add and subtract \displaystyle\left(\frac{b}{2a}\right)^2. Factor the perfect square trinomial \cos\left(3x\right)^2+6\cos\left(3x\right)+9.
