Question

A.-2pq(3p2 - 4pg - 7q2)
b.a2(6a2 - 2a + 5b2)
c.(4x - 3) (5x - 2)
d.16x6y8 : (4x3y2 X 2x2y4)
e.(x3 + x2 - 10x - 6) : (x - 3)

angka yang tebal = pangkat

Answer 1

A. (-2pq)(3p²) + (-2pq)(-4pq) + (-2pq)(-7q²) = -6p³q + 8p²q² + 14pq³
b. (a²)(6a²) + (a²)(-2a) + (a²)(5b²) = 6a4 -2a³ + 5a²b²
c. (4x)(5x) + (4x)(-2) + (-3)(5x) + (-3)(-2) = 20x² - 8x - 15x + 6 = 20x² - 23x + 6
d. 16x6y8 : 8x5y6 = 2xy²
e. x² + 4x + 2
