Question

Pls answer this question with steps

Answer 1

Step-by-step explanation:

2(sin⁶+cos⁶)-3(sin⁴+cos⁴)+1

2{(sin²)³+(cos²)³}-3(sin⁴+cos⁴)+1

2{(sin²+cos²)(sin⁴+cos⁴-sin²•cos²)-3(sin⁴+cos⁴)+1

2(sin⁴+cos⁴-sin²•cos²)-3(sin⁴+cos⁴)+1

2sin⁴+2cos⁴-2sin•cos-3sin⁴-3cos⁴+1

-sin⁴-cos⁴-2sin²•cos²+1

-(sin⁴+cos⁴+2sin²•cos²)+1

-(sin²+cos²)²+1

-(1)²+1

-1+1
