Free factor calculator Factor quadratic equations stepbystepThe maximum/minimum point (also known as the "vertex") can be found as follows The xcoordinate of this point is The a is the coefficient of the term and the b is the coefficient of the term In your equation, a = 1 and b = 2, so This is the xcoordinate of the vertexTo find the ycoordinate for the vertex we plug in h in the original equation k = a(h) 2 b(h) c Plot the points and graph the parabola Example 1) Graph y = x 2 2x 8 In this problem a = 1, b = 2 , and c = 8 Since "a" is positive we'll have a parabola that opens upward (is U shaped)
For any parabola, Ax2BxC, the x coordinate of the vertex is given by B/ (2A) In our case the x coordinate is Plugging into the parabola formula for x we can calculate the y coordinate y = 10 * 100 * 100 * 100 70 or y = 6000 Answer vertex (1,9) x intercepts (4,0) (2,0) Comment;Divide 0 0 by − 8 8 Multiply − 1 1 by 0 0 Add 8 8 and 0 0 Substitute the values of a a, d d, and e e into the vertex form a ( x d) 2 e a ( x d) 2 e Set y y equal to the new right side Use the vertex form, y = a(x−h)2 k y = a ( x h) 2 k, to determine the values of a a, h h, and k k
Divide 22\sqrt {y} by 2 The equation is now solved Swap sides so that all variable terms are on the left hand side Factor x^ {2}2x1 In general, when x^ {2}bxc is a perfect square, it can always be factored as \left (x\frac {b} {2}\right)^ {2} Take the square root ofDescription Learn to complete the square in order to write quadratic equations in vertex form Learning Objectives Stepbystep explanation y = x^2 2x 8 The axis of symmetry is h = b/2a h = 2/ (2*1) = 2/2 =1 x = 1 The x coordinate of the vertex is at the axis of symmetry To find the y value substitute into the function y
