**How to solve polynomial equation word problem?**

Example:

A tree is supported by a wire anchored in the ground 5 feet from its base. The wire is 1 foot longer than the height that it reaches on the tree. Find the length of the wire.
**Polynomial equation word problem**

Example:

A gymnast dismounts the uneven parallel bars. Her height, h, depends on the time, t, that she is in the air as follows:

h = -16t^{2} + 8t + 8

a) How long will it take the gymnast to reach the ground?

b) When will the gymnast be 8 feet above the ground?

**How to solve word problems with polynomial equations?**

Examples:

1. The sum of a number and its square is 72. Find the number.

2. The area of a triangle is 44m^{2}. Find the lengths of the legs if one of the legs is 3m longer than the other leg.

3. The top of a 15-foot ladder is 3 feet farther up a wall than the foo is from the bottom of the wall. How far is the ladder from the bottom of the wall?

4. A projectile is launched upward from ground level with an initial speed of 98m/s. How high will it go? When will it return to the ground?**How to write Polynomials for Word Problems?**
