Question

Verify 2 and 3 are zeros of x2-5x+6

Answer 1

Answer:

2 is a zero of x2 - 5x + 6

3 is not a zero of x2 - 5x + 6

Step-by-step explanation:

2 and 3 are zeros of x2 - 5x + 6

$x2-5x+6\\Given: x=2\\2(2) - 5(2)+6\\4 - 10 +6\\4+6-10\\10-10 = 0$

∴ 2 is a zero of x2 - 5x + 6

$x2 - 5x + 6 \\Given: x=3\\(3)2 - 5(3) + 6 \\6-15+6\\12-15\neq 0$

∴ 3 is not a zero of x2 - 5x + 6

Hence, verfied
