Step-by-step explanation:
1) px² + qx + rx⁴ + 5 is biquadratic [ highest power is 4 ]
2) 3x² + 7 is a polynomial
3) zero of polynomial 2x + 5 is -5/2
4) value of k is -3
5) zero
6) if 3 + 5 - 8 = 0, then 3³ + 5³ +(-8)³ = 3×3×5×(-8)
=> -360
7) 104 × 96
=> (100 + 4)(100 - 4) => 100² - 4² => 10000 - 16
=> 9984
