It equals x2 - 34
2x2 + x2 = 3x2
x2 + x2 = 2x2 2x^2
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.
572 Because 2x11=22 and 13x2=26 and 22x26=572.
x+x=2x
x2 + x2 + x2 = (1 + 1 + 1)x2 = 3x2
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
1920
x2 + x2 = 48 2x2 = 48 x2 = 24 x = √24 x = 2√6
200 + 640 + 390 = 1270
x2 + x2 = 2x2
