(11-x)^2
Expanding the square of (11-x), we get:
(11-x)^2 = (11-x)(11-x)
= 11(11) - 11x - 11x + x(x)
= 121 - 22x + x^2
Therefore, (11-x)^2 = 121 - 22x + x^2.
To simplify the expression (11-x)^2, you can use the formula for expanding a binomial expression.
Step 1: Square the first term, which is 11.
(11)^2 = 121
Step 2: Multiply the product of the two terms by twice the product of the two terms. Since the two terms are 11 and -x, the product is -11x.
2 * (11) * (-x) = -22x
Step 3: Square the second term, which is -x.
(-x)^2 = x^2
Putting it all together, we have:
(11-x)^2 = 121 - 22x + x^2
Therefore, the simplified expression is 121 - 22x + x^2.
