What is the difference between linear and quadratic equations? A linear equation has the form of mx + b, while a quadratic equation's form is ax2+bx+c. Also, a linear equation's graph forms a line, while a quadratic equation's graph forms a parabola. Why does quadratic equation called...

determine the equation of a quadratic functionconditions: x-intercept 3, and passing through the point (1,-2) 相关知识点: 试题来源: 解析 It sounds like that it passes thru 3 points: (0, 0), (3, 0), (1, -2)From the first 2 points, it can be expressed in the form of y = ...
3. the product of x and y . The product of the (two) roots of a quadratic equation ax^2+bx+c=0 equals the constant c divided by the quadratic coefficient a, i.e. \dfrac{c}{a} . 4. 除法(Division) Division is the inverse operation of multiplication. 12\div 4=3 means when 12...
4) make sure you write the final version of the equation (only variables should be x and y) Vertex Form of the Quadratic Function: y = a(x-h) + k or f(x) = a(x-h) + k 2 2 Vertex is ( 3 , -2) 3...what makes bracket (partial factor) zero...the “h” -2... th...
x3=A+B+3AB3(A3+B3)=3xAB3+A+B. Comparing this with the given equation x3=ax+b will give a=3AB3=3β3 and b=A+B=α. It will thus become α=b and β=a327; whence the quadratic equation serving for the resolution of the equation x3=ax+b in the explained way will be z2...
What is the equation for the axis of symmetry of a quadratic function y = 3x² + 6x + 2? A. x = -1 B. x = -2 C. x = -3 D. x = -4 相关知识点: 试题来源: 解析 A。解析:For the function y = 3x² + 6x + 2, a = 3 and b = 6. Using the formula x = -b/...
$$$(x-1) \cdot (x+3)=x^2-x+3x-3=x^2+2x-3$$$We have returned to the original equation. So "the product of $$x$$ minus a root multiplied by $$x$$ minus the other root is equal to the quadratic equation that has these roots as a solution". Example If the solutions of...
