Answer 1

Answer:

$4x^2 + 9y^2 -12xy$

Step-by-step explanation:

$=(2x-3y)^2$

Using $(a-b)^2 = a^2+b^2-2ab$

$= (2x)^2 + (3y)^2 - 2(2x X 3y)\\= 4x^2 + 9y^2 -12xy$

Answer 2

We know that...

(a-b)²=a²+b²+2ab

(2x-3y)²=(2x)²+(3y)²-2(2x)(3y)

=4x²+9y²-12xy....

e) 105²= 100²+5²

=10000+25

=10025

f) 99²=100²-1²

=10000-1

=9999

These are answers
