What is \( 12x^2 - 9x + 15 \)?

12x² - 9x + 15
It can be written as . . .
3 ( 4x² - 3x + 5 )
but that's just a different way to write the same thing. It doesn't tell you anything new, until you know what number 'x' is.

The expression 12 x 2 − 9 x + 15 can be simplified by factoring out the common factor of 3 to give 3 ( 4 x 2 − 3 x + 5 ) . The quadratic part inside the parentheses has a negative discriminant, indicating there are no real roots. Thus, the expression in its simplest form is 3 ( 4 x 2 − 3 x + 5 ) .
