18 + 81 = 9(x²<span> + 6x + 9)
</span><span>11 = (x + 3)</span>²
When we are completing the square, we are going to move the value of c across the equals. We will do that by adding, and end up with
18=9(x²+6x)
We take the value of b (the coefficient of x), divide it by 2 and square it:
(6/2)²=3²=9
This is the value that completes the square. However, since the entire square is multiplied by 9, this value must be multiplied by 9 before we can add it across the equals:
18+9(9) = 9(x²+6x+9)
18+81=9(x²+6x+9)
99=9(x²+6x+9)
Dividing both sides by 9, we have:
11=x²+6x+9
11=(x+3)²

Answer:</h2>
The ice cream was ₹15
<h2>
Step-by-step explanation:</h2>
This is because the amount that was not given after Anjana gave the ₹50 note for ice cream is what the ice cream costed.
In this instant, we can use the ₹35 which was returned to Anjana, and substract it from ₹50, to get ₹15, which all together equals ₹50 and means that Anjana spend ₹15 on ice cream.
