What are the roots of the quadratic equation 0 = 2x^2 + 12x –14?2, 12, –14–7, 1–1, 71, 6, –7Can you explain what it is wanting or asking?
Accepted Solution
A:
It is basically asking you to find where the equation crosses the d-axis. 2x^2 + 12x -14 = (x-1)(2x-14). x-1=0. x=1. 2x-14=0. 2x=14. x=7. The solution/roots/zeros would be 1 and 7
