Jovan is building a fort in his backyard using a 10-foot board. He leans the base of the board 6 feet away from the
base of the wall. How high will the board be able to reach
up the wall? If necessary, round to the nearest tenth.

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

answer: it is 8
