The teacher has written an equation of the form  on the board, where  is a quadratic, but Heather can't read the linear term. She can see that the quadratic term is  4x^2 and that the constant is -24. She asks her neighbor, Noel, what the linear term is.

Noel decides to tease her and just says, ``One of the roots is 3.''

Heather then says, ``Oh, thanks!''

She then correctly writes down the linear term. What was the linear term? Include entire term, not simply the coefficient.

4x2+ax24=0244=r1r2|r1=3244=3r2r2=2412r2=2a4=(r1+r2)a4=(32)a=4

 

4x24x24
