Question

Find the zero of polynomial 7x+5

Answer 1

`x=-5/7`

Explanation:

we have

`f(x)=7x+5` ----> The degree of this polynomial is 1 (linear equation)

Remember that

The zero of the polynomial is the value of x when the value of f(x) is zero

so

For f(x)=0

`0=7x+5`

solve for x

`x=-5/7` ----> the zero of the polynomial or x-intercept
