Example 3. Graph the quadratic equation y = 3 x2 + x – 3. Let's find the useful things. Other than duct tape, a Swiss army knife, and a compass. We meant more within the realm of algebra. We should have been clearer. What are the intercepts? To find the x -intercepts, we need to use the quadratic equation
Quadratic Equations | Solved Problems and Practice
The following are examples of some quadratic equations: 1) x 2 +5x+6 = 0 where a=1, b=5 and c=6. 2) x 2 +2x-3 = 0 where a=1, b=2 and c= -3. 3) 3x 2 +2x = 1 → 3x 2 +2x-1 = 0 where a=3, b=2 and c= -1. 4) 9x 2 = 4 → 9x 2-4 = 0 where a=9, b=0 and c= -4 . For every quadratic equation, there can be one or more than one solution.Author: MBA Crystal Ball

Solving quadratic equations by factoring examples
Solving quadratic equations by factoring examples. Example 1 : Solve x² + 9 x + 14 = 0. Solution : Since the coefficient of x ² is 1, split the constant term that into two parts. 14 = 2 ⋅ 7, 2 + 7 = 9 x² + 9 x + 14 = 0 (x + 2) (x + 7) = 0. x - 2 = 0 x + 7 = 0. x = 2, x = -7. Hence the solution is {2, -7}
