$144x^2 - 36 x + \frac{9}{4}$ can be expressed as the square of ____________. |
$14x -\frac{3}{2}$ $12x -\frac{9}{4}$ $12x -\frac{3}{2}$ $12x - 9$ |
$12x -\frac{3}{2}$ |
We know that, (a - b)2 = a2 + b2 - 2ab 144x2 - 36x + \(\frac{9}{4}\) = (12x)2 - 2(12x)( \(\frac{3}{2}\)) + (\(\frac{3}{2}\))2 (12x - \(\frac{3}{2}\))2 = (12x - \(\frac{3}{2}\)) |
