Factor this trinomial completely. -12x^2+45x+12
Amanda [17]

Step-by-step Answer:

Step 1:

Extract factor(s) common to all terms.

In this case, the HCF is 3, so the expression is written

-12x^2+45x+12 = -3(4x^2-15x-4)

The negative sign was also exrracted to give a positive leading coefficient, which is easier to work with.

Step 2, group the coefficient in such a way that there is a common factor.

Leaving the factor -4 for the moment, and concentrate on the coefficients in parentheses, write the original expression as

4x^2 - 15x -4  

= 4x^2 -16x

          +   x -4

= 4x*(x-4) + 1*(x-4)

extract (x-4) as a common factor

= (x-4)(4x+1)

Step 3:

Combine all the factors to get

-3(x-4)(4x+1)

=3(4-x)(4x+1)

as the complete factoring of the given expression.
