प्रश्न

Find the roots of the quadratic equation `x^2 - (sqrt(3) + 1)x + sqrt(3)` = 0.

योग

उत्तर

The given equation is `x^2 - (sqrt(3) + 1)x + sqrt(3)` = 0

⇒ `x^2 - sqrt(3)x - x + sqrt(3)` = 0

⇒ `x(x - sqrt(3)) - 1(x - sqrt(3))` = 0

⇒ `(x - 1) (x - sqrt(3))` = 0

⇒ `(x - 1)` = 0 or `(x - sqrt(3))` = 0

x = 1 or x = `sqrt(3)`

Hence, x = 1, `sqrt(3)` are the roots of the given quadratic equation.

One of the roots of equation kx2 – 10x + 3 = 0 is 3. Complete the following activity to find the value of k.

Activity:

One of the roots of equation kx2 – 10x + 3 = 0 is 3.

Putting x = `square` in the above equation

∴ `"k"(square)^2 - 10 xx square + 3` = 0

∴ `square` – 30 + 3 = 0

∴ 9k = `square`

∴ k = `square`


Determine whether (x – 3) is a factor of polynomial x3 – 19x + 30.

Let P(x) = x3 – 19x + 30

By remainder theorem, `square` will be a factor of P(x), if P(3) = 0

Now, P(3) = `square` – 19 `square` + 30

= `square  –  square` + 30

= `square  –  square`

= 0

∵ P(3) = 0

Hence, `square` is a factor of polynomial x3 – 19x + 30.
