we get the equation

x^{2} +15x+56.25 =105.25

We have given that the function

x^{2} +15x=49

<h3>What is the condition for complete ting square method?</h3>

for completing the squares , we have to add both sides the square of half of coefficient of x

So we add both sides (\frac{15}{2})^{2}

Or,

(7.5)^{2}

add both side 7.5 square in given equation

x^{2} +15x+7.5^{2} =49+7.5^{2}

x^{2} +15x+56.25 =105.25

Therefore,we get the equation

x^{2} +15x+56.25 =105.25
