Answer:
not possible
Step-by-step explanation:
The point lies directly on the regression line (Apex)
Factor it should be
8(v-8)(v+7)
Simply you can substitute theta=45 degrees (or any angle,not zero) in left hand side and right hand side.
or
using a^2 - b^2 =(a+b)(a-b)
= sin(2x+x)sin(2x-x)
= sin 3x sin x
