Answer 1

Answer:

1 st is correct ,mark me as a breanliast

Answer 2

Given:

A quadratic polynomial 2x²-16.

To Find:

The zeroes of the given polynomial:

Solution:

The given problem can be solved using the concepts of quadratic expressions.

1. A quadratic expression is said to have a zero when that corresponding value of x equals the expression to 0.

2. Zeroes of 2x² - 16 is,

=> 2x² - 16 = 0,

=> 2x² = 16,

=> x² = 16/2,

=> x² = 8,

=> x = √8,

=> x = 2√2, -2√2.

Therefore, Option A is the correct answer. The zeroes of the polynomial are 2√2, -2√2.
