Question

p²x - 2{px – 3х(х2² – За – х²)} ​

Answer 1

Answer:

P2x – 2{px – 3x (x2 – (3a – x2 )}

= p2x – 2{px – 3x (x2 – 3a – x2)}

= p2x – 2{px – 3x (2x2 – 3a)}

= p2x – 2{px – 6x3 + 9ax}

= p2x – 2px + 12x3 – 18ax

Answer 2

Answer:

P2x – 2{px – 3x (x2 – (3a – x2 bar))}

= p2x – 2{px – 3x (x2 – 3a – x2)}

= p2x – 2{px – 3x (2x2 – 3a)}

= p2x – 2{px – 6x3 + 9ax}

= p2x – 2px + 12x3 – 18ax
