*(2a +5 )( 3a -6)*

**6 a^2 - 12 a + 15 a - 30**

[because , 2a is multiplied with 3a , 2a is multiplied with -6 , +5 is multiplied with 3a and +5 is multiplied with -6][because , 2a is multiplied with 3a , 2a is multiplied with -6 , +5 is multiplied with 3a and +5 is multiplied with -6]

*6 a^2 + 3 a - 30 (answer)*

[because , -12a is subtracted from +15a][because , -12a is subtracted from +15a]

= 6a2 + 3a – 30

= 3(2a2 + a – 10)

= 3(2a2 + a – 10)
