Question

Which represents x2 – 12x + 36 in factored form?

Answer 1

(x - 6)(x - 6)

Explanation:

The given quadratic equation is
`$ x^2 - 12x + 36 = 0 $`.

A quadratic equation can be factored in the form
`$ (x - a)(x - b) $` where
`$ -a $` and
`$ -b $` will form the roots of the equation.

Here the roots are:
`$ +6 , +6 $`.

The factored form would simply be:
`$ (x - 6) (x - 6) $`.
