Explain how you would use the
technique of completing the square to
solve the following:
x2 + 6x – 16 = 0

two solutions

x1=-8 , x2=2

Step-by-step explanation:

x^{2}+6x-16=0 move constant to the right

x^{2}=6x=16 add () to both sides of question

x^{2}+6x+()=16+()

x^{2}=6x+()=16+()

using a^{2}+2ab+b^{2}=(a+b)^{2}, factor the expression

[tex](x+\frac{6}{2} ^{2}=25

reduce the fraction with 2

(x+3)^{2}=25

solve for x

the get final solution of x= -8 and x= 2

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
