It equals x2 - 34
2x2 + x2 = 3x2
If by "what is the answer to" you mean, "how do you factor", then there is no answer, as this expression can not be factored. If you're asking to solve for x where the expression above is equal to zero, then x is equal to 16.
x2 + x2 = 2x2 2x^2
572 Because 2x11=22 and 13x2=26 and 22x26=572.
Assuming you wish to make this equation equal zero, for x2 + 16x + 55 = 0, x = -5.
x2+xx = 15 Which is the same as: x2+x2 =15 2x2 = 15 x2 = 7.5 x = the square root of 7.5
x+x=2x
x2 + x2 + x2 = (1 + 1 + 1)x2 = 3x2
x2 + x2 = 48 2x2 = 48 x2 = 24 x = √24 x = 2√6
1920
200 + 640 + 390 = 1270
x2 + x2 = 2x2
