Question

Use the graph to find the factorization of x - 7x+12. 5 y=x2.7x + 12 5 O A. (x - 3)(x - 4) B. (x-6)(x-8) C. (x+ 6) (x + 8) O D. (x+3)(x + 4)

Answer 1

The roots of the quadratic equation can be obtained from the points where the graph crosses the horizontal axis

From the graph, we can see that the x-axis was crossed at the points x = 3 and x = 4

What this means is that the root of the quadratic equation are at the points x = 3 and x = 4

The factorization is thus; (x-3)(x-4)
