I need help with the following problems:

Siplify 1/3(3x) + [(-5x) + (5x)]

Simplify and write with positive exponents

xy^5

_____

x^3y

Simplify

√6x^2 * √30x

Factor Completely

324x^2 - 36y - 180x^2 + 20

Factor Completely

49x^2 + 28x + 4

Solve and Check

2[7x + 2 + 4(x + 1)] = -4x + 1

Solve by factoring

3x (x-4) = 5x^2 - 13x

Solve by using the square root method

(11x - 4)^2 = 12

AND LASTLY

SOLVE BY USING THE QUADRATIC FORMULA

3x^2 = -12x - 2
