Tolong jawab dikumpulkan bsk,, No 9 b, c, d, e, f,, (pakai cara lengkap ya)

9.)B. M-3/5+m+7/10
=2m-6/10+m+7/10
=3M+1/10
C. 3/m+5/m2
=3m+5/m2
D. m+1/6-m-1/4
=2m+2/12-3m-3/12
=-m+5
Sisa nya itung sendiri ya saya lg mau ngerjain pr dulu

9.
a. [tex] \frac{m-3}{5} + \frac{m+7}{10} [/tex]
dikalikan 10
[tex] 10. \frac{m-3}{5} + 10. \frac{m+7}{10} [/tex]
2(m-3) + m + 7
= 2m - 6 + m +7
= 3m + 1

b. [tex] \frac{3}{m} + \frac{5}{m^{2} } [/tex]
kalikan [tex] m^{2} [/tex]
[tex] m^{2} . \frac{3}{m} + m^{2} . \frac{5}{ m^{2} } [/tex]
=m(3) + 5
= 3m + 5

d.[tex] \frac{m+1}{6} - \frac{m-1}{4} [/tex]
kalikan 24
= [tex]24. \frac{m+1}{6} - 24. \frac{m-1}{4}[/tex]
= 4(m+1) - 6(m-1)
= 4m + 4 - 6m + 6
= -2m + 10

e. [tex]\frac{m-2}{8} - \frac{1-3m}{12}[/tex]
kalikan 96
= [tex]96. \frac{m-2}{8} - 96. \frac{1-3m}{12}[/tex]
= 12(m-2) - 8(1-3m)
= 12m-24 - 2 + 24m
=26m - 26

f.[tex]\frac{5}{6m} - \frac{m+1}{3m^{2} }[/tex]
kalikan 6m²
[tex]6m^{2}. \frac{5}{6m} - 6m^{2}.\frac{m+1}{3m^{2} }[/tex]
= m(5) - 2(m+1)
= 5m - 2m - 2
= 3m - 2

10.
(x+2)(x+5)
= x² + 2x + 5x + 10
= x² + 7x + 10

(2x + 3)(x - 1)
= 2x² + 3x + 2x - 3
= 2x² + 5x - 3
