Chapter 1 - 1.2 - Linear Equations in One Variable - 1.2 Exercises - Page 89: 73

False

$$x(3-x)=10$$ Simplifying the equation: $$3x-x^2=10$$ $$x^2-3x+10=0$$ Notice that the degree of the left side expression is $2$ which is for quadratic and not $1$ which is for linear equation. Thus, the statement is false.
