4x - 7 + 3 = 0
Combine like terms: 4x - 4 = 0
Add 4 to both sides: 4x = 4
Divide both sides by 4: x = 1
many solutions
8x2 + 16x + 8 = 0
x=-.25.
-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
X = 1.8
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.
