X2 plus 6x-2 equals -2x2 plus x?
x2 plus 6x-2 equal -2x2 plus x ..=7x equal -3x2 ..4x=2x=2 answer ..check it if u dont want to trust ..Improved Answer:x2+6x-2 = -2x2+xx2+2x2+6x-x-2 = 03x2+5x-2 = 0(3x-1)(x+2) = 0x = 1/3 or x = -2The answer can be checked by using the quadratic equation formula.
What is the vertex of the parabola represented by the equation y equals 2x 24x-100?
Assuming you mean y=2x(24x-100)=48x2-200xThe vertex is the coordinate (p,q) when a function of a form y=ax2+bx+c is arranged into the form y=a(x-p)2+q.Divide y by the coeifficient of the x2 term, 48. y = x2-(25/6)xx2-ax = (x-a/2)2-a2/4.So y = [x-(25/6)/2]2-(625/36)/4 = [x-25/12]2-625/144y is now in the form y=a(x+p)2+q, so the vertex of 48x2-200x is (25/12, -625/144)
