Question

The degree of the equation x² – 2x + 1 = x² – 3 is

  1. 1
  2. 2
  3. 0
  4. 3

The correct answer is: 1


    1 space i s space t h e space c o r r e c t space c h o i c e
space x ² space – space 2 x space plus space 1 space equals space x ² space – space 3
f i r s t space l e t apostrophe s space s o l v e space i t
space x ² space – space 2 x space plus space 1 space equals space x ² space – space 3
space x ² minus space x ² equals negative 3 minus 1 plus 2 x
0 space equals space 2 x space minus space 4
2 x space equals space 4 space
s o space x equals 2
x minus 2 space equals 0
s o space t h e space d e g r e e space o f space t h e space e q u a t i o n space x minus 2 space equals space 0 space comma space i s space bold 1 bold comma
