Question

(x-3)2 степень=? (a-5)2 степень=? (8-x)2 степень=? Плиз

Answer 1

(x-3)^2=x^2-6x+9

(a-5)^2=a^2-10a+25

(8-x)^2=64-16x+x^2

Answer 2

(х-3)^2= х^2-6х+9

(а-5)^2= а^2-10а+25

(8-х)^2=64-16х+х^2

^2 - это во второй степени

Answer 3

To expand the expressions, we'll use the formula for squaring a binomial:

For any binomial (a + b)^2, the expansion is: (a + b)^2 = a^2 + 2ab + b^2.

Let's apply this formula to the given expressions:

1. (x - 3)^2: Expanding (x - 3)^2 using the formula, we get: (x - 3)^2 = x^2 + 2(x)(-3) + (-3)^2 = x^2 - 6x + 9

2. (a - 5)^2: Expanding (a - 5)^2 using the formula, we get: (a - 5)^2 = a^2 + 2(a)(-5) + (-5)^2 = a^2 - 10a + 25

3. (8 - x)^2: Expanding (8 - x)^2 using the formula, we get: (8 - x)^2 = 8^2 + 2(8)(-x) + (-x)^2 = 64 - 16x + x^2

So, the expanded expressions are:

1. (x - 3)^2 = x^2 - 6x + 9
2. (a - 5)^2 = a^2 - 10a + 25
3. (8 - x)^2 = x^2 - 16x + 64
