"-3" is not a solution. Further explanation is given below.
Step-by-step explanation:
Given:
(x-2)²-3x-10=0 and,
x= -3
On putting the value of "x" in the above equation, we get
⇒ (-3-2)²-3×(-3)-10=0
⇒ (-5)²+9-10=0
⇒ 25+9-10=0
⇒ 34-10=0
⇒ 24 ≠ 0
"24" is not equal to "0". Therefore, "-3" is not a solution of the given equation.
