Question: Make the given changes in the indicated examples of this section and then solve the resulting equations by the quadratic formula. In Example 1, change

Make the given changes in the indicated examples of this section and then solve the resulting equations by the quadratic formula.

In Example 1, change the − sign before 5x to +.


Data from Example 1

Solve:

= x x2 a = 1 I b 5x + 6 -5


Here, using the indicated values of a, b, and c in the quadratic formula, we have


c = 6 || 0.


The roots x = 3 and x = 2 check when substituted in the original equation.

= x x2 a = 1 I b 5x + 6 -5 c = 6 || 0.
