Answer 2

Answer:

2a⁴+a²b²-15b⁴

Step-by-step explanation:

For multiplying the given binomials, first we have to multiply 2a² with (a²+3b²) and -5b² with (a²+3b²) i.e..

= 2a²(a²+3b²) -5b²(a²+3b²)

= 2a⁴+6a²b² -5a²b²-15b⁴ [sings are changed. Since, before Braket there is negative (-) sing]

= 2a⁴+a²b²-15b⁴[6a²b²-5a²b²=a²b² Since, unlike terms eliminate]

Hope you understand
