Question

The sum of the zeroes of the polynomial p(x) = 5x − 7x² + 3 is ______.

Options

• `(-7)/5`

• `7/5`

• `5/7`

• `(-5)/7`

Answer 1

The sum of the zeroes of the polynomial p(x) = 5x − 7x² + 3 is `underlinebb(5/7)`.

Explanation:

To find the sum of the zeroes of the given polynomial p(x) = 5x - 7x² + 3, we use the formula:

`"Sum of zeroes" = - "Coefficient of x"/("Coefficient of" x^2)`

Here, the polynomial is p(x) = −7x² + 5x + 3.

Sum of zeroes = `-5/-7`

= `5/7`
