Complete the square to write y = 3x^2 + 12x + 7 in vertex form, y = a(x - h)^2 + k. y = 3(x^2 + 4x) + 7
y = 3(x^2 + 4x + 4) + 7 -

When the above expression is written in vertex form, a is [-5 , -2, or 3], h is [-5, -2, or 3], and k is [-5, -2, or 3].

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)

    5

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =
