Solve the equation: x2 + 8x + 16 = 49 Enter the smallest zero value. Use a number only.
x2 + 8x + 16 = 49 using a^2 +2ab + b^2 = (a+b)^2 we get (x+4)^2 = 7^2 x+4 = ±7 x=3 or x=-11
Solve the equation: (x + 1)2 = 9. Enter the largest zero value. Use a number only.
it is just the same!! can you try it?
