A formula is a type of equation, but usually one that relates common quantities in a standard way that can be applied to solve other problems, such as the quadratic formula used to solve quadratic equations, or the relationship described by the Pythagorean theorem that relates the lengths of t...
Use the quadratic formula to solve the equation. {eq}\displaystyle 4 x^2 - 4 x - 4 = 0 {/eq} Quadratic Formula: The quadratic formula is one of the easiest techniques out of all known techniques (factoring, completing the square, quadratic formula) for finding the roots/ ...
Solve each equation using the quadratic formula. -4x^2+2x+3=0 相关知识点: 试题来源: 解析 x= (\ 1± √ (13))4 -4x^2+2x+3=0, so a=-4, b=2, c=3.x= (-(2)±√ (2^2-4(-4)(3)))(2(-4))= (-2± √ (52))(-8)= (\ 2± √ 4√ (13))8= (\ 2± 2√ (...
Quadratic Formula: The quadratic formula is a formula that is applied to determine the roots of any quadratic equation whose standard form is {eq}ax^2+bx+c=0 {/eq}. It is given by the formula {eq}x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a} {/eq}. Answer and Explanation...
