We have the algebraic expression: 12x2 - 18x - 21
First multiply coefficient of x2 with -21. The result is -21 x 12 = -252.
Now, break down coefficient of x into two numbers such that their product is -252.
-18 can't be broken into two numbers such that their product is -252.
So, 12x2 - 18x - 21 can't be factorized.
Another Answer:-
It appears that the above quadratic expression can be factored because its discriminant is greater than zero.
12x2-18x-21
Divide all terms by 3:
4x2-6x-7 = (4x+3.08276253)(x-2.2706906326) when factored correct to 8 and 10 decimal places respectively
