Question

*I need this done in a few minutes*

*Are these equivalent? Can you please show the work to explain if they are or not? I'm confused about how to do the squared coefficients.*

Is 7x - 4 + 2x² + 6 + 3x² equivalent to 7x + 1 + 5x² + 1?

*Please show the work so I can understand*

Answer 1

combine like terms

combine the x^2 terms and compare the left side and right side

2x^2 + 3x^2 = 5x^2

5x^2 = 5x^2

combine the constant terms, those without x or any variable

6-4 = 1+1

2=2

what's left is 7x which appears on both sides

7x = 7x

the two expressions are equivalent

everything on the left side equals what's on the right side
