Sederhanakanlah!
1. 3 (2×+7) =
2. 7×+2y - 3×+4y =
3. (3×+5y) (7×-7y) =
4. (3×+5y) - (8×-2y) =
5. (3y-2) + (7y-4) =
1. 3 (2×+7) =
2. 7×+2y - 3×+4y =
3. (3×+5y) (7×-7y) =
4. (3×+5y) - (8×-2y) =
5. (3y-2) + (7y-4) =
Jawaban:
1. 3(2x + 7) = 6x + 21
2. 7x + 2y - 3x + 4y = 4x + 6y
3. (3x + 5y)(7x - 7y) = 21x^2 - 14xy + 35xy - 35y^2 = 21x^2 + 21xy - 35y^2
4. (3x + 5y) - (8x - 2y) = 3x + 5y - 8x + 2y = -5x + 7y
5. (3y - 2) + (7y - 4) = 3y + 7y - 2 - 4 = 10y - 6
Jawaban:
Mari kita sederhanakan masing-masing ekspresi:
1. 3(2x + 7) = 6x + 21
2. 7x + 2y - 3x + 4y = 4x + 6y
3. (3x + 5y)(7x - 7y) = 21x^2 - 14xy - 35xy + 35y^2 = 21x^2 - 49xy + 35y^2
4. (3x + 5y) - (8x - 2y) = 3x + 5y - 8x + 2y = -5x + 7y
5. (3y - 2) + (7y - 4) = 3y + 7y - 2 - 4 = 10y - 6
