8x2 + 16x + 8 = 0
-y + y equals 0.
2x(3x+6) = 0 x = 0 or x = -2

8x2 + 16x + 8 = 0
-y + y equals 0.
x2 plus 3x plus 3 is equals to 0 can be solved by getting the roots.
a2+30a+56=0 , solve for a Using the quadratic formula, you will find that: a=-2 , a=-28
y= -2x
-1 plus 1 = 0 plus 1 =1
2x(3x+6) = 0 x = 0 or x = -2
c= -2 2/7 OR -2.285714
p is obviously zero because any number x plus 0 equals itself.
x = 4 and y = 0
x^(2) - 10x + 16 = 0 Factors of '16', which are, 1,2,4,8,16. Select two numbers from this list that add/subtract to '10' . They are '2' and '8'. Setting up brackets ( x 2)(x 8) Since '16' is positive(+), then both signs must be the same. Since '10x' is negative (-) , then both signs are negative. Hence (x - 2)(x - 8 ) = 0 When x - 2 = 0 x = 2 & when x - 8 = 0 x = 8 So the two answers are ,2, & ,8, .
