Assuming you mean 12x2 - 5x - 2, use the reverse FOIL method. But, first, multiply the two end number together (12 * -2 = -24). Then find two numbers whose product is -24 and sum is -5. These two numbers are 3 and -8.
3 * ( -8 ) = -24 and 3x + ( -8x ) = -5x
Next, we use those factors found in the previous step and group them together.
12x2 - 5x - 2
12x2 + 3x - 8x -2
( 12x2 + 3x ) ( -8x - 2 )
Next, take out the common factors from each group
( 12x2 + 3x ) ( -8x - 2 )
3x ( 4x + 1 ) - 2 ( 4x + 1 )
Lastly, group the two ungrouped terms multiplied by their common factor ( 4x + 1 )
3x ( 4x + 1 ) - 2 ( 4x + 1 )
( 3x - 2 ) ( 4x + 1 )
Next, we check the work by usingthe FOIL method.
( 3x - 2 ) ( 4x + 1 )
F ... 3x * 4x = 12x2
O ... 3x * 1 = 3x
I ... -2 * 4x = -8x
L ... -2 * 1 = -2
12x2 + 3x - 8x - 2
Combine like terms
12x2 - 5x - 2
Start by looking for a common factor. Separate this factor, then factor the remaining polynomial.

If there is no common factor then the polynomial cannot be factorised. If there is no common factor then the polynomial cannot be factorised. If there is no common factor then the polynomial cannot be factorised. If there is no common factor then the polynomial cannot be factorised.
Factor the polynomial x2 - 10x + 25. Enter each factor as a polynomial in descending order.
In algebra, the factor theorem is a theorem linking factors and zeros of a polynomial. It is a special case of the polynomial remainder theorem.The factor theorem states that a polynomial has a factor if and only if
