Step-by-step explanation:
a).
(2x-3y)(2x-3y)
=(2x-3y)²
=(2x)²+(3y)²-2*2x*3y
=4x²+9y²-12xy
b).
(3x²-2y²)(3x²-2y²)
=(3x²-2y²)²
=(3x²)²+(2y²)²-2*2x²*3y²
=9x⁴+2y⁴-12x²y²
c).
(1/2x-1/5y)(1/2x-1/5y)
=(1/2x-1/5y)²
=(1/2x)²+(1/5y)²-2*1/2x*1/5y
=1/4x²+1/25y²-1/5xy
d).
(2/3x²-5)(2/3x²-5)
=(2/3x²-5)²
=(2/3x²)²+5²-2*2/3x²*5
=4/9x⁴+25-20/3x²
