sedrhanakan bentuk aljabar berikut.. 4b + 5a - 7b - 2a - 3b = 3p + 2q + 1 - 2p + 4q + 6 = 2m(4m-3) - 3(m-2n) = 7y + 3x(4y - x) - 5y(1 - x) + 5 x^2 =

-3b + 3a - 3b = - 6b + 3a

4b + 5a - 7b - 2a - 3b
= 5a - 2a + 4b - 7b - 3b
= 3a - 6b

3p + 2q + 1 - 2p + 4q + 6
= 3p - 2p + 2q + 4q + 1 + 6
= p + 6q + 7

2m(4m - 3) - 3(m - 2n)
= [(2m . 4m) - (2m . 3)] - [(3.m) - (3 . 2n)]
= [8m² - 6m] - [3m - 6n]
= 8m² - 6m - 3m + 6n
= 8m² - 9m + 6n

7y + 3x(4y - x) - 5y(1 - x) + 5x²
= 7y + (3x . 4y) - (3x . x) - (5y . 1) + (5y . x) + 5x²
= 7y + 12xy - 3x² - 5y + 5xy + 5x²
= 2x² + 17xy + 2y
