Let’s say and write the following algebraic expressions as the perfect square forms.
E.g.
$a^2 + 2.a.b + b^2 = (a + b)^2$
$(3x)^2 – 2.3x.5 + 5^2 = (3x – 5)^2$
| Algebraic Expressions | Perfect Square Forms |
| a) $x^2 + 2.x.y + y^2$ | |
| b) $m^2 + 2.m.1 + 1^2$ | |
| c) $p^2 + 2.p.3 + 3^2$ | |
| d) $(2a)^2 + 2.2a.3b + (3b)^2$ | |
| e) $m^2 – 2.m.n + n^2$ | |
| f) $x^2 – 2.x.5 + 5^2$ | |
| g) $(2x)^2 – 2.2x.7 + 7^2$ | |
| h) $(3x)^2 – 2.3x.5y + (5y)^2$ |
