Question

Find the zero of the polynomial
`f(x) = 2x + 3`​.

Answer 1

To find the zeros, equate the given expression to zero ,

`\bf \Large \hookrightarrow \: \: 2x \: + \: 3 \: = \: 0`

`\bf \Large \hookrightarrow \: \:2x \: = \: - 3`

`\bf \Large \hookrightarrow \: \:x \: = \: ( - 3)/(2) \\`

Zero of the polynomial is -3/2

Answer 2

• Lets take f(x)=0

`\\ \sf\longmapsto f(x)=0`

`\\ \sf\longmapsto 2x+3=0`

`\\ \sf\longmapsto 2x=-3`

`\\ \sf\longmapsto x=(-3)/(2)`

Which is the zero of the polynomial
