So, we are now going to solve quadratic equations. First, the standard form of a quadratic equation is \[a{x^2} + bx + c = 0\hspace{0.25in}a e 0\] The only requirement here is that we have an \({x^2}\) in the equation. We guarantee that this term will be present in the equation by requiring \(a e 0\).Let's look particularly at the factorizations \((2x-3)(x + 5) = 0\) and \((9x + 2)(7x - 3) = 0\)/ The next step is to set each factor equal to zero and solve. We can solve mentally if we understand how to solve linear equations: we transpose the constant from the variable term and then divide by the coefficient of the variable.Section 2.5 : Quadratic Equations - Part I. For problems 1 – 7 solve the quadratic equation by factoring. u2 −5u−14 = 0 u 2 − 5 u − 14 = 0 Solution. x2 +15x =−50 x 2 + 15 x = − 50 Solution. y2 = 11y−28 y 2 = 11 y − 28 Solution. 19x = 7−6x2 19 x = 7 − 6 x 2 Solution. 6w2 −w =5 6 w 2 − w = 5 Solution. z2 −16z +61 = 2z ...2. The graph of y = 4x2 – 2x + 7 will be a parabola opening downward since the coefficient of x2 is positive. 3. A quadratic function’s axis of symmetry is either the x-axis or the y-axis. 4.

The graph of a quadratic function opening upward has no maximum value. 5. The x-intercepts of the graph of a quadratic function are the solutions to the related quadratic equation. 6. All quadratic equations have two real solutions. 7. Any quadratic expression can be written as a perfect square by a method called completing the square. 8. Definitions: Forms of Quadratic Functions. A quadratic function is a function of degree two. The graph of a quadratic function is a parabola. The general form of a quadratic function is f(x) = ax2 + bx + c where a, b, and c are real numbers and a ≠ 0. The standard form of a quadratic function is f(x) = a(x − h)2 + k.Try It 9.50. Solve by using the Quadratic Formula: 3 y ( y − 2) − 3 = 0.
