4.409 x 10^-6
move the decimal 6 places to the right
Answer: 2 + √10 , 2 − √10
Step-by-step explanation:
-5x(x-4) = -30
divide by -5
x(x - 4) = -30
distribute the x
x^2 - 4x = 6
move the 6 to the left to have the equation equal zero
x^2 - 4x - 6 = 0
plug into the quadratic formula & solve
x
= 2 + √10 , 2 − √10
