2a²-2ab-3b²+9 when a=3 and b=2​

Sagot :

  • a=3,b=2

[tex]\\ \sf\longmapsto 2a^2-2ab-3b^2-9[/tex]

[tex]\\ \sf\longmapsto 2(3)^2-2(3)(2)-3(2)^2-9[/tex]

[tex]\\ \sf\longmapsto 2(9)-12-3(4)-9[/tex]

[tex]\\ \sf\longmapsto 18-12-12-9[/tex]

[tex]\\ \sf\longmapsto 6-18[/tex]

[tex]\\ \sf\longmapsto -12[/tex]

Answer:

3

Step-by-step explanation:

2(3)^2 - 2(3)(2) - 3(2)^2 + 9

2(9) - 12 - 3(4) + 9

18 - 12 - 12 + 9

= 3
