Indicate by T or F whether the equations below are equivalent to a linear equation.

Question

Indicate by T or F whether the equations below are equivalent to a linear equation.
1. x 2 −5x+4=x 2 +6x−11 
2. 3x+4=5x−4 
3. 1x+3 =12x−3  
4. x 2 +1=x−x 2 

Answer 1

all equivalent to linear except last

1. 11x=15 is a linear equivalent as the x^2 terms cancel out
2. x = 4 is linear & an equivalent
3. 11x=6 is linear & equivalent
4. 2x^2 -x +1 is quadratic, also it can't be factored into linear factors
