Hi there!
Since square roots are non-negative, Inequality is only meaningful if both sides are non-negative. Hence, squaring both sides was indeed valid.
Similarly, applying a decreasing function toboth sides of an in- equality will reverse it.
Cheers!
I'm assuming the question is asking for you to factor the expressions.
b.
(x-3)(x+2)
-3+2=-1
-3*2=-6
d.
(x-6)(x-7)
-6-7=-13
-6*-7=42
