A straight line = 180 degrees.
Subtract the 2 known angles from 180:
180 - 112 - 38 = 30 degrees
We are asked to factor out the expression:
4 x^3 - 10 x
So we extract a factor of "2" from the numerical factors "4" and "10", and also a factor of "x" from each term,leading to:
2 x ( 2 x^2 - 5)
Therefore, please select the first answer option they give you in the list.
