(.200-x)2
Would the answer be .400+x2
no, .200-2x
arrrrggggg.
.400-2x
Close. .400 is right and it's -2x
So .400 - 2x
You could make it easier and write
.4 - 2x
How is it 2x?
it couldn't be 2x could it, because the whole thing is squared not times two? The question looks like (.200-x)squared?
You have to write it as an exponent if squared
(.2-x)^2
.04 + .4 x + x^2
To find the answer to the expression (.200 - x)², you need to apply the exponent rule for squaring a binomial.
The formula for squaring a binomial is: (a - b)² = a² - 2ab + b²
So, in this case, a = 0.200 and b = x.
Using the formula, we can find the answer step by step:
(.200 - x)² = (.200)² - 2(.200)(x) + (x)²
= 0.040 - 0.400x + x²
Therefore, the correct answer would be 0.040 - 0.400x + x².
