This value is very different from the other values
No they do not have the same number of zeroes
Although the 2 products do seem like they might have the same number of zeroes, 40 x 500 and 40 x 600
both have 3 zeroes before multiplying
if we take the first 2 digits of the 2 numbers being multiplied to get an idea of the answer
if we take 40 x 500 - 4 x 5 = 20
then theres an extra zero added
but if we take 40 x 600 - 4 x 6 = 24
no extra zeroes added to this
so if we finally look at the answers
40 x 500 = 20 000
40 x 600 = 24 000
20000 has 4 zeroes and 24000 has 3 zeroes
so the answer is no they dont have the same number of zeroes
Let u = x², then we would have u² + 5u - 6 = 0
From here, we can factor it and get us (u-1)(u+6) = 0
So our solution for u is u = -6 or 1.
Now substitute u back to x².
x² = -6 or 1
x = ±√(-6) or ±√1
Since ±√(-6) is not real number, we ignore it.
Which leave us x = ±√1 = <span>±1
So our real solution is x = -1 or 1.</span>
