You have the following numbers: 1, 2, 3, 4, 5. Using these numbers, write at least 10 different mathematical expressions. Use at
1 answer:
Mathematical expressions allow us to relate numbers using mathematical symbols to make calculations. some examples are:
- 2 + 3 = 5
- 4 - 1 = 3
- 2 × 2 = 4
- 4 ÷ 2 = 2
- 2² + 1 = 5
- (1 + 2) + (2 × 1) = 5
- (2 + 3) - 4 = 1
- (2 + 2)² ÷ 4 = 4
- (2 ÷ 4)² × 4 = 1
- (2 + 2)² (4 ÷ 2) - (2 × 4)(5 - 1) + 5 = 5
A mathematical expression is a sequence of characters that are intended to express a general relationship between the terms expressed in the formula.
Mathematical expressions generally have symbols like:
- Add +
- Subtraction -
- Multiplication ×
- Division ÷
- Exponent
- Equal =
- Parentheses ()
According to the above, some examples of mathematical expressions are:
- 2 + 3 = 5
- 4 - 1 = 3
- 2 × 2 = 4
- 4 ÷ 2 = 2
- 2² + 1 = 5
- (1 + 2) + (2 × 1) = 5
- (2 + 3) - 4 = 1
- (2 + 2)² ÷ 4 = 4
- (2 ÷ 4)² × 4 = 1
- (2 + 2)² (4 ÷ 2) - (2 × 4)(5 - 1) + 5 = 5

Answer:
x⁴ - 11x² + 28
= x⁴ - 4x² - 7x² + 28
= x²(x² - 4) - 7(x² - 4)
= (x² - 7)(x² - 4)
