Question
Evaluate the following without multiplying:$(95)^2$
✓
Answer
Using $(x + y)^2$
$= x^2+ 2xy + y^2,$
we get
$(95)^2$
$= (100 - 5)^2$
$= (100)^2 - 2(100)(5) + (5)^2$
$= 10000 - 1000 + 25$
$= 9025.$
$= x^2+ 2xy + y^2,$
we get
$(95)^2$
$= (100 - 5)^2$
$= (100)^2 - 2(100)(5) + (5)^2$
$= 10000 - 1000 + 25$
$= 9025.$
