Question

if zero of the polynomial ax-10 is 5,then find the value of ‘a’

Answer 1

⇒x=5

⇒5a−10=0

⇒5a=10

∴ a= 10/5 =2

Answer 2

Given polynomial: $ax-10=0$

also, given zero of this polynomial that is $x=5.$

Therefore, by placing the value of $x$ in the given polynomial, we get:

$ax-10=0$

$a\times5-10=0$

$a\times5=10$

$a=\frac{10}{5}$

$a=2.$

The value of $a=2.$
