Question

expand these (x/2-y/3)²​

Answer 1

Answer:

Step-by-step explanation:(x/2-y/3)2

=x2+4-y2+9-4xy-12y+6x

Answer 2

Concept :

We must multiply out the brackets in order to extend and simplify an expression. The resulting phrase is then made simpler by grouping like terms together. We take out brackets by expanding them, often known as multiplying out. A number can be written in expanded form by multiplying the sum of its digits. When determining the worth of a number's digits, we can utilise a place value chart.

Given:

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

Find:

expansion of the equation

Solution:

According to the problem,

$(x/2 - y/3) ^2\\= x^2/4 - 2xy/6 + y^2/9$

Hence the answer is $x^2/4 - 2xy/6 + y^2/9$
