Rewrite the equation by completing the square. 4 x^{2} - 12 x + 9 = 04x 2 - 12x+9=0

(2x - 3) ^2 = 0

Step-by-step explanation:

In this particular instance, the square is already complete. The rewrite is to show that.

(2x - 3) ^2 = 0

__

In the general case, ...

(ax + b) ^2 = a^2x^2 + 2abx + b^2

Comparing this form to the given left-side expression, we see that ...

a = 2, b = - 3

So, the trinomial is already a perfect square trinomial.
