A 28-foot ladder is leaning against a building in such a way that it also touches the top of an
8-foot fence. The bottom of the ladder is 6 feet
from the base of the fence. The fence is 8 feet
from the building. How high is the top of the
ladder on the building?

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
