MATH 1010-2: Quiz 3A
... (a) We are going to find solutions among real numbers greater than or equal to −1. In this case, x + 1 is always positive or 0. So it’s always true that |x + 1| = x + 1. The original equation becomes x+1=4 whose solution is x = 3. Since 3 > −1, it’s in the area that we are finding solutions. (b) We ...

Maple Lecture 26. Solving Equations
... The main command to solve equations is solve: [> equ := a^2*(x^2+x+1)-a*(2*x-3)-x^2-3*x+2; [> sols := solve(equ,x); Maple returns us two roots, but we have to be careful: the denominator in the solutions may vanish. We investigate what the equation looks like for this special parameter value: [> equ ...
