Answer 1

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
