Question

If the zero of polynomial ax-10
is 5 then the value of a is
A) 2
B) - 2
c) -1
D)1​

Answer 1

Since 5 is the zero of ax-10
Therefore 5a-10=0
5a=10
a=2

Answer 2

Answer:

heya mate ☺

➡ Given, Zero oF the polynomial ax - 10 = 5

So,

$ax - 10 = 0 \\ \\ = > a(5) - 10 = 0 \\ \\ = > 5a - 10 = 0 \\ \\ = > 5a = 10 \\ \\ = > a = \frac{10}{5} \\ \\ = > a = 2$

So option (a) is correct.
