Question

What are the zeros of the quadratic function f(x) = 2x2 + 16x – 9?

Answer 1

Step-by-step explanation:

1. $2 \times 2 + 16x - 9 = f(x) \\ we \: will \: find \: zero \\ 2 \times 2 = 4 \\ 16x - 9 = 0 \\ 16x - 9 + 4 = 0 \\ 16x - 5 = 0 \\ 16x = 5 \\ boths \: divide \: y \: 16 \\ x = 5 \div 16 = ..........$
