x = the square root of -1, an imaginary number written as a lower case italic i.
many solutions
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
x+2=3/(x+2) (x+2)(x+2)=3 xx+4x+4=3 xx+4x+1=0 USE QUADRATIC x+2=3/x+2 x=3/x xx=3 x=sqrt(3),-sqrt(3)
Isolating xx = (6+6)/32x = 0.375
-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
