Answer 1

terms and multiply it out: ... cos(x+y)cos(x-y)=(cosxcosy)^ 2+sinxsinycosxcosy- ... sin^2y+cos^2y=1 and sin^2x+cos^2x=1 ... Can you

Answer 2

Answer:

4x2+12y2−4x−2

Step-by-step explanation:

Let's simplify step-by-step.

(2x−1)2−3(1−2y)(1+2y)

Distribute:

=4x2+−4x+1+12y2+−3

Combine Like Terms:

=4x2+−4x+1+12y2+−3

=(4x2)+(12y2)+(−4x)+(1+−3)

=4x2+12y2+−4x+−2

Answer:

=4x2+12y2−4x−2
