2(3x-4) = 5x+6 First, expand the bracket. 6x-8=5x+6 Next, move the variables to the same side. x-8=6 Move the -8 to the other side, change to + x=6+8 x=14 Charlie’s solution is incorrect. When expanding the bracket, he changed the - to a +.
Rewrite the function in vertex form,y = (a - h)² + k, and identify the coordinates of the vertex and equation of axis of symmetry.Show Work y = -3x² - 24x - 50
