ANSWER
Polynomials!
_________________________________
1. 7x + 2x + 19x = 28x
Collect like terms by calculating the sum or the coefficients
7x + 2x + 19c
Just calculate the sum, like this
(7 + 2 + 19) x
Final answer = 28x
_________________________________
2. 6x - 3 + 3x - 9 = 3(3x - 4)
Collect like the terms to calculate
6x - 3 + 3x - 9
Factor the expression
9x - 12
Final answer = 3(3x - 4)
_________________________________
3. (3x - 4y) - (x + 2y) = 2(x - 3y)
Remove the parenthesis
(3x - 4y) - (x + 2y)
Collect like terms
3x - 4y - x - 2y
So, Factor the expression
2x - 6y
Final answer = 2(x - 3y)
_________________________________
4. 18x⁵ ÷ 6x³ = 3x⁸
Divide the given
18x⁵ ÷ 6x³
Then, calculate them
3x ⁵ × x³
Final answer = 3x⁸
________________________________
5. (x ÷ 5) (x - 7) = 1/5x² - 7/5x
Transform them, into this
(x ÷ 5) × (x - 7)
Need to Rewrite the expression
(1/5 x) × (x - 7)
Then, remove the parenthesis
1/5x × (x - 7)
Final answer = 1/5x² - 7/5x
