factorise 3*x^2-12*x
Let's factorize in <math><mi>ℝ</mi></math>: <math><mn>3</mn><msup><mrow><mi>x</mi></mrow><mrow><mn>2</mn></mrow></msup><mo> -</mo><mn>12</mn><mi>x</mi></math>
You can write the expression in factored form: <math><mi>x</mi><mo>·</mo><mo>(</mo><mn>3</mn><mi>x</mi><mo> -</mo><mn>12</mn><mo>)</mo></math>
Let's factor in <math><mi>ℝ</mi></math>: <math><mo>(</mo><mn>3</mn><mi>x</mi><mo> -</mo><mn>12</mn><mo>)</mo></math>
