i need only answer plz tell
if anyone help me​

Answer 1

Answer:

(1/2x)^2 - 2.1/2x.3/2y + (3/2y)^2

= 1/4 x^2 + 3/2xy + 9/4y^2

Answer 2

$\huge\mathfrak\blue{Answer:}$

Given:

• We have been given a expression :
• ${(\dfrac{1}{2}x - \dfrac{3}{2}y)}^{2}$

To Find:

• We have to find the expansion of given algebric expression

Solution:

We have been given :

$= > {(\dfrac{1}{2}x - \dfrac{3}{2}y)}^{2}$

$= > {( \dfrac{x}{2} - \dfrac{3y}{2} )}^{2}$

Expanding the expression using ( a + b )²

$=> { (\dfrac{x}{2}) }^{2} + {( \dfrac{3y}{2}) }^{2} - 2 \times \dfrac{x}{2} \times \dfrac{3y}{2}$

$= > \dfrac{ {x}^{2} }{4} + \dfrac{9 {y}^{2} }{4} - 2 \times \dfrac{x}{2} \times \dfrac{3y}{2}$

$= > \dfrac{ {x}^{2} }{4} + \dfrac{9 {y}^{2} }{4} - \dfrac{3xy}{2}$

Above is the required expansion
