Question

The zeroes of the polynomial p(x) = 25x² – 49 are ______.

Options

• `49/25, 49/25`

• `-49/25, 49/25`

• `7/5, -7/5`

• `7/5, 7/5`

Answer 1

The zeroes of the polynomial p(x) = 25x² – 49 are `underlinebb(7/5, -7/5)`.

Explanation:

p(x) = 25x² = 49

= (5x – 7)(5x + 7)

∴ x = `7/5` and `(-7)/5`
