The expression is simplified to give 2 ( m² + m + 2Im ) = 0
<h3>
How to simplify the expression</h3>
Given the expression;
(1+m)²= (1-m)²+ 4lm,
Expand the expression
( 1 +m) ( 1 + m) = ( 1 + m) ( 1 - m) + 4Im
1 + m + m + m² = 1 - m + m - m² + 4Im
collect like terms
1 + 2m + m² = 1 - m² + 4Im
1 - 1 + m² + m² + 2m + 4Im
2m² + 2m + 4lm = 0
simplify
2 ( m² + m + 2Im ) = 0
Thus, the expression is simplified to give 2 ( m² + m + 2Im ) = 0

I believe it’s A
Sorry if I get it wrong :/
<u><em>Answer:</em></u>
Number of child tickets sold that day = 25 tickets
<u><em>Explanation:</em></u>
Assume that the number of the adult ticket is x and that the number of the child ticket is y.
<u>We are given that:</u>
1- four times as many adult tickets as child tickets were sold. <u>This means that:</u>
adult tickets = 4 * child tickets
x = 4y ....................> equation I
2- Child ticket costs $5.5, adult ticket costs $9.1 and total sales was $1047.5.
<u>This means that:</u>
x(9.1) + y(5.5) = 1047.5
9.1x + 5.5y = 1047.5 ..................> equation II
<u>Substitute with equation II in equation I and solve for y as follows:</u>
9.1x + 5.5y = 1047.5
9.1(4y) + 5.5y = 1047.5
36.4y + 5.5y = 1047.5
41.9y = 1047.5
y = 25
<u>Based on the above calculations:</u>
number of child tickets = y = 25 tickets
number of adult tickets = x = 4y = 4(25) = 100 tickets
Hope this helps :)
I can't read that, Can you write out the question?
