Completing the square is done as follows:
1. Write the equation in a way that the constants are in the right side while the terms with x are on the left.
<span>9x2 +54x = 7
</span>
2. Make sure that the coefficient of the x^2 term is 1.
<span>9(x2 + 6x) = 7
</span>
3. Adding a term to both sides that will complete the square in the left side. This is done by dividing the coefficient of the x term by 2 and squaring it. Note: The same amount should be added to the right side to balance the equation.
<span>9(x2 + 6x + 9) = 7 + 81
9(x+3)^2 = 88
</span>
Answer:
10.63cm
Step-by-step explanation:
Pythagorean theorem
a^2+b^2=c^2

Answer:
(p-q)(1+x)
Step-by-step explanation:
p-q-x(q-p)
p-q-xq+xp
p+xp-q-xq
p(1+x)-q(1+x)
(p-q)(1+x)
