Prove '2xy is less than equal to x2 plus y2'?
(x - y)2 >= 0 since the left hand side is a square. ie x2 - 2xy + y2 >= 0 so x2 + y2 >= 2xy
The difference between 2x squared plus 4xy - 3 and x squared - 2xy - 4?
(2x2+4xy-3)-(x2-2xy-4)Answer: x2+6x+1
When x-y equals 7 and xy equals 8 find the value of x square plus y square?
x2 + y2 = x2 - 2xy + y2 + 2xy = (x - y)2 + 2xy = 72 + 2*8 = 49 + 16 = 65 You could, instead, solve the two equations for x and y and substitute, but the above method is simpler.
What is the formula of square of binomial?
(x + y)2 = x2 + 2xy + y2
