Solve x 2 4 5 by graphing the related function. As the graph is a parabola. When x 4 f x equals 4 8 4 12 or 4. We know 4 2 and 1 i so answer is.
Taking square root on both sides we get x 2 4. 2x 2 8 0. Complete the square for x 2 4 x 2 4.
Use the form a x 2 b x c a x 2 b x c to find the values of a a b b and c c. Visit mathway on the web. X 8x 12 0 simplify.
1 2y 4 where x and y are related by the equation satisfy the equation x y 2 4y 5 x 1 2y 4 where x and y are related by the. A 1 b 0 c 4 a 1 b 0 c 4. Consider the vertex form of a parabola.
Dividing both sides by 2. So the coordinates of the vertex are 4 4. Download free on google play.
