Answer:

1. x = 0, 4, -9

2. x = 3, 3, -5

3. 2x^3 - 9x^2 + 7x + 6

4. x = -6, -8, -15

5. 2x^3+10x^2+12x

Factor out the common factor:

2x (x^2+5x+6 )

Factor what's left in parentheses:

2x (x + 2) (x + 3)

6. x = 0, 4, -9

Again using the Pythagorean Theorem:

h^2=x^2+y^2, where h is the hypotenuse of a right triangle and x and y are the side lengths. You are given that the hypotenuse is 34 ft and the base side is 16ft. Let h=34, x=16, and y=height, then you have:

34^2=16^2+y^2

y^2=34^2-16^2

y^2=1156-256

y^2=900

y=√900

y=30 ft

So the ladder will reach a spot 30 feet high on the building.
