Factor completely: 4x2 + 25x + 6 (4x + 1)(x + 6) (4x + 6)(x + 1) (2x + 3)(2x + 2) (2x + 6)(2x + 1)

    General quadratic equation \[ax^2+bx+c=0\] Here we have \[4x^2+25x+6\] So what's a , b and c here?

    Now b is 25 here Can you find factors of 24, which add up or subtract to form 24 ?

    Let me rephrase it, 2 factors of 24 which add up or subtract to form 25?
