Consider the equation: 6x + 55 = x^2
1) Rewrite the equation by completeing the square.
2) Choose the solutions
x = -3 ± 8
x = 3 ± 8
x = -8 ± 3
x = 8 ± 3

Find the value of 1715⋅211.though these numbers aren't quite as nice as the ones from the example or the previous part, the procedure is the same, so this is really no more difficult. give the numerator followed by the denominator, separated by a comma.

Agroup of students want to create a garden. they do not know the exact measurements but they propose using a variable to represent the length and width of the garden. the length of the garden is 10 feet longer than double the width. use a single variable to write algebraic expressions for both the length and width of the garden. write an algebraic expression for the area of the garden. use mathematical terms to describe this expression.
