-4 x -4 = +16 = 16 -4 + -4 = -8
1 x 16, 2 x 8, 4 x 4
4² x 4³ = 16 x 64 = 24 + 40 + 360 + 600 = 1,024
x^2 - 8x + 16 = 0(x )(x )You need two numbers that when multiplied are equal to 16, and when added are equal to 8.These two numbers are 4 and 4 (4 * 4 = 16, 4 + 4 = 16)Then you need to figure out if these are positive or negative. Since 16 is positive, you know that the numbers are either both positive or both negative. Since the 8 is negative, you know they must be negative.(x - 4)*(x - 4)
No, because 8x8 is 64, not 16. The solution is 4 or -4.
