Question

write the expansion of ( 3/2x - 5/3y + 3z) ²​

Answer 1

Answer:

$(3 \div 2x - 5 \div 3y + 3z) ^{2}$

$(3 \div 2x) ^{2} + ( - 5 \div 3y) ^{2} + (3z) ^{2} + 2 \times 3 \div 2x \times ( - 5 \div 3y) + 2( - 5 \div 3y \times 3z) + 2 \times 3z \times 3 \div 2x$

$9 \div 4x ^{2} + 25 \div 9y ^{2} + 9z ^{2} - 5xy - 10yz + 9zx$
