Mark is solving the equation 4x^2 = 12x - 9 using the quadratic formula.
which values could he use for a, b and c?
a = 4, b = 12, c = -9
a = 4, b = -9, c = 12
a = 4, b = 9, c = -12
a = 4, b = -12, c = 9

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)
