Answer the following questions:
2x5=10
11.If f(x) = x^2 - 4x + 3 find the zeros of the polynomial of f(x)​

Answer 1

Answer:

1 and 3

Step-by-step explanation:

Given a quadratic polynomial such that,

f(x) = x^2 - 4x + 3

To find it's zeroes.

We have to convert it into an equation.

Therefore, we will get,

=> f(x) = 0

=> x^2 - 4x + 3 = 0

Now, we will factorise it.

For that, we will use middle term splitting method.

Therefore, we will get,

=> x^2 - 3x - x + 3 = 0

Taking out common terms, we get,

=> x(x-3) -1(x-3) = 0

=> (x-3)(x-1) = 0

Therefore, we will get,

=> x - 3 = 0

=> x = 3

And

=> x - 1 = 0

=> x = 1

Hence, required zeroes are 1 and 3 .
