ASSIGNMENTS

PROJECT #1. Work only equations (a) and (c), but complete all 6 steps (a-f) as shown in the example. An interesting method for solving quadratic equations came from India. The steps are;

You should be concise in your reasoning.

(a). Move the constant term to the right side of the equation.

(b). Multiple each term in the equation by four times the coefficient of the x^2 term.

(c). Square the coefficient of the original x term and add it t both sides of the equation.

(d). Take the square root of both sides.

(e). Set the left side of the equation equal to the positive square root of the number on the right side and solve for x.

(f). Set the left side of the equation equal to the negative square root of the number on the right side of the equation and solve for x..

Equations to solve;

(a). x^2 – 2x – 13 = 0

(c). x^2 + 12x – 64 = 0

PROJECT #2. Please select at least five numbers; 0 (zero), two even, and two odd of your choice. Make sure you organize your paper into separate projects. Use the same steps to solve project #2 as well.
