1. It seems that the simplest numbers, like -1, 0, and 1, can be#the hardest to identify as coefficients of a quadratic equation.#Rewrite the equations to the right in standard form so that#the values of a, b, and c are easy to identify. Then write#down the values of a, b, and c.
2. Why can╒t we find the roots of a quadratic equation if the discriminant (the number under the radical sign in the quadratic formula) is negative? Why can╒t we find the square root of a negative number?
3. Apply the quadratic formula to find the roots of the quadratic equation ╥u times x-squared plus vx plus w equals 0,╙ in terms of u, v, and w.
