We convert to improper fraction to get:

We now deal with the parenthesis by multiplying with the reciprocal of 2.

This gives:

We multiply to get:

This simplfies to:

We write as mixed number

Answer:
2x³ + 17x² + 41x + 30 = (x + 5) (x + 2) (2x + 3)
Step-by-step explanation:
2x³ + 17x² + 41x + 30 = (x + 5) (2x² + ax + 6) =
2x³ + (a + 10) x² + (5a + 6) x + 30
a + 10 = 17 a = 7 ( check: 5a + 6 = 5 x 7 + 6 = 41)
2x³ + 17x² + 41x + 30 = (x + 5) (2x² + 7x + 6) = (x + 5) (x + 2) (2x + 3)
The two angles are 45 degrees.
Step-by-step explanation:
You are just halfing the 90 degree angle, so all you have to do is divide 90 by two, and you have 45.
