Question

simplify (cos theta + cos theta)^2 + (cos theta + cos theta)^2

Answer 1

\(\large\color{midnightblue}{ \rm (cosθ + cosθ)^2 + (cosθ + cosθ)^2 }\) like this ?

Answer 2

\(\large\color{midnightblue}{ \rm (cosθ + cosθ)^2 + (cosθ + cosθ)^2 }\)

\(\large\color{midnightblue}{ \rm (2cosθ)^2 + (2cosθ)^2 }\)

\(\large\color{midnightblue}{ \rm 2(2cosθ)^2 }\)

\(\large\color{midnightblue}{ \rm 2(2cosθ)(2cosθ) }\)

\(\large\color{midnightblue}{ \rm 2(4cos^2θ) }\)

\(\large\color{midnightblue}{ \rm 8cos^2θ }\)
