y2 - 5y = 3
Weegy: y^2+5y+6=0 y^2+3y+2y+6=0 y(y+2)+2(y+3)=0 (y+2)(y+3)=0 y+2=0 - - - - - > y = -2 y+3=0- - - - - - - -> y = -3 solution set y = -2 and -3 User: x2 + 6x = - 9. Hint: This is a double root. Weegy: x=2 is the answer. User: (x - 8)2 = 48 Weegy: The simplify answer for this problem is x to the second power/4 -y to the second power User: Solve 2x 2 - 7x - 15 = 0. Weegy: the answer is 25 User: Identify the following series as arithmetic, geometric, both, or neither. -3 + 3 - 3 + 3 - 3 + . . . Weegy: Geometric User: Evaluate C(4, 4) Weegy: 4! = 4 x 3 x 2 x 1 = 24. [smile] User: How many subsets of three elements each exist in a set of six elements? 3!

(x - 8)^2 = 48
x - 8 = ± sqrt 48
x - 8 = ± 4 sqrt 3
x = 8 ± 4 sqrt 3

x^2 - 49 = 0
(x + 7)(x - 7) = 0
x = -7 or x = 7

y^2 + 7y = 18
y^2 + 7y - 18 = 0
(y - 2)(y + 9) = 0
y - 2 = 0 or y + 9 = 0
y = 2 or y = -9
the equation that could be used to solve y^2+7y=18 by factoring is y - 2 = 0 and y + 9 = 0
