Question

2 Draw the graph of y = x2 - 4x +3 and use it to solve x² - 6x + 9 = 0​

Answer 1

Step-by-step explanation:

To solve: x2 + 3x – 4 = 0 subtract x2 + 3x – 4 = 0 from y = x2 + 3x – 4, The points of intersection of the parabola with the x axis are the points (-4, 0) and (1, 0), whose x – coordinates (-4, 1) is the solution, set for the equation x2 + 3x – 4 = 0.Read more on Sarthaks.com - https://www.sarthaks.com/941081/draw-the-graph-of-y-x-2-3x-4-and-hence-use-it-to-solve-x-2-3x-4-0-y-2-x-3x-4
