Infinity.
x² + x² = 2x²
It is a polynomial expression in x. What about it?
(x+y)^2+z^2=x^2+y^2+z^2+2xy or ((x+y)^2+z)^2= (x^2+y^2+2xy+z)^2= x^4+y^4+z^2+6x^2y^2+4x^3y+2x^2z^2+4xy^3+4xyz^2+2z^2y^2
x^3+y^3 Cube root of the first, x plus cube root of the last, y times What it takes to make the first number, x^2 Opposite sign, - Product of the two cube roots, -xy Then what it takes to make the last. (x+y)(X^2-xy+y^2)
3x^2 + x + 2x^2 = 5x^2 + x
(x+y)power 2 -2xy
A similar question can be solved as below : If x to the power 4 plus 1 upon x to the power 4 equals 23 then what will be (x minus 1 upon x) to the power 2 equals what?a2 + b2 = (a + b)^2 - 2ab.so (x^2 )^2 + (1/x2)^2 = (x^2 + 1/x^2)^2 - 2 = 23.so (x^2 + 1/x^2) = 5.therefore(x - 1/x)^2 = (x^2 + 1/x^2) -2 = 5 -2 = 3.
10 ( x = -3)
x = +11 or -11
92,054,000 is the answer.
(x^2 - 3x + 5)(x^2 + 3x + 5)
2x + 3x = 25 → x ≈ 2.663844636
(x^2 - 2x + 2)(x^2 + 2x + 2)
(x + 1)(x^2 - x + 1)
576
6^3 + 2^4 = (6 x 6 x 6) + (2 x 2 x 2 x 2) = 216 x 16 = 3456
