It is used often as an example of something that is obviously false especially in popular culture. It is a reference to the book 1984 by George Orwell
2 squared is 4 3 cubed is 27 27 plus 4 is 31
The quadratic expression x2+6x+8 when factorised equals (x+2)(x+4)
2(2)2 + 3(2)(- 4) - 4(- 4)2 8 - 24 - 64 = - 80 ======
You use Plus as a symbol in Maths. Example, 2 Plus 2 equals 4. Or in symbols it would be 2+2=4. __________________________ Plus = + Equals = = (Equals equals =)
Factors are (y + 4)(y - 2) so if the original expression = 0 then y is either 2 or -4
no if 1 plus 1 equals 2 then 2 plus 2 equals 4.
Equals 4, Not 32 + 2 equals 4, not 3.No, 2 plus 2 is 4.
22 = 4
4
No because it contains an equal sign in it.
26
No.
