Question

Find the zeroes of the following polynomials: (a) x² - 5x (b) 3x - 8​

Answer 1

Answer:-

1). The zeroes of x² - 5x are [x=5 or x-5=0]

2). The zeroes of 3x-8 are [ x=8/3 or x -8/3=0]

Step By Step Explanation:-

In context to the given question; we have to find the zeroes of the two polynomial

That means;

We have to find those value of x by which the polynomial becomes zero

For that we have to equate the polynomial with zero

Therefore;

1). x² - 5x

By equating with zero; we get

x² - 5x= 0

x² = 5x

By cutting one one x on both the side

We get;

x=5

The zeroes of x²- 5x are [x=5 or x-5=0]

2). 3x -8

By equating with zero; we get

3x -8 =o

3x=8

x= 8/3

The zeroes of 3x-8 are [ x=8/3 or x -8/3=0]
