2 Question Rewrite the equation y=–2x^24x3 in vertex form Identify the vertex and the axis of symmetry Answer by ewatrrr(243) (Show Source) You can put this solution on YOUR website!Divide 4, the coefficient of the x term, by 2 to get 2 Then add the square of 2 to both sides of the equation This step makes the left hand side of the equation a perfect square Square 2 Add y1 to 4 Factor x^ {2}4x4 In general, when x^ {2}bxc is a perfect square, it can always be factored as \left (x\frac {b} {2}\right)^ {2} Y=x^2-4x 1 in vertex form

Steps for Solving Linear Equation y=2x2 y = 2 x 2 Swap sides so that all variable terms are on the left hand side Swap sides so that all variable terms are on the left hand side 2x2=y 2 x 2 = y Subtract 2 from both sides Subtract 2 from both sidesApr 11,  · math Graph the quadratic functions y = 2x^2 and y = 2x^2 4 on a separate piece of paper Using those graphs, compare and contrast the shape and position of the graphs I would suggest you graph the two functions on the same grid, not on separate pieces of paper You will be able to answer the questions so much easierAug 05, 16 · See the explanation Suppose x=3 then 2x2=8 So the inequality of y Graph Of Y 2x 2 Y x 2 2 x 3

Expand X X Y 3 3xy X Y  This is a sum of cubes This is a semiimportant identity to know #(x^3y^3)=(xy)(x^2xyy^2)# Although it doesn't apply directly to this question, it's alsoEx 25, 9Verify (i) x3 y3 = (x y) (x2 – xy y2)LHS x3 y3We know (x y)3 = x3 y3 3xy (x y)So, x3 y3 = (x y)3 – 3xy (x y) = (x y)3 – 3xy Differentiate y 2 x
