(tanθ + cotθ)² = sec²θ + csc²θ
<u>Expand left side</u>: tan²θ + 2tanθcotθ + cot²θ
<u>Evaluate middle term</u>: 2tanθcotθ =  = 2
 = 2
⇒ tan²θ + 2+ cot²θ
 = tan²θ + 1 + 1 + cot²θ
<u>Apply trig identity:</u>  tan²θ + 1 = sec²θ 
⇒ sec²θ + 1 + cot²θ
<u>Apply trig identity:</u>  1 + cot²θ = csc²θ
⇒ sec²θ + csc²θ
Left side equals Right side so equation is verified

-10x + 1.5 because you get rid of the parenthesis so -2 times 5 is -10 ( -10x ) and then -2 times -0.75 equals positive 1.5 due to two negatives canceling out to positive hope this helped!
