23y-11y = 12y
y(3y^2 - 12y + 4)
2y2 + y = -11yAdd 11y to each side of the equation:2y2 + 12y = 0Divide each side by 2:y2 + 6y = 0Factor the left side:y (y + 6) = 0The equation is true if either factor is zero:y = 0or (y + 6) = 0y = -6
Pull out the common factor of 2 ... 2(y^2+6y-16) Then just factor (y^2+6y-16) ... (y-2)(y+8)
4(3y+4)
23y-11y = 12y
y(3y^2 - 12y + 4)
Y=10
(x + 11y)(x - 12y)
(x + 15)(x - 3)
2y2 + y = -11yAdd 11y to each side of the equation:2y2 + 12y = 0Divide each side by 2:y2 + 6y = 0Factor the left side:y (y + 6) = 0The equation is true if either factor is zero:y = 0or (y + 6) = 0y = -6
12y3 - 30y2 + 12yFactor out a y:y(12y2 - 30y + 12)Factor out a 6:6y(2y2 -5y + 2)Factor 2y2 - 5y + 26y(2y - 1)(y - 2)
12Y + 9 all I can see to factor out is 3 3(4Y + 3)

5x=11y
Well, honey, to factor 4x + 12y, you can start by taking out the greatest common factor, which in this case is 4. So you're left with 4(x + 3y). And that's all she wrote!
