1.  Linear = polynomial is in first degree (the leading term has exponent 1)

2  Write in standard form:  -r² - 4r + 25 = 0   
   Quadratic, second -degree polynomial (the leading terms has exponent 2)

3.  Write in standard form:  x² - 5x + 10 = 0   
     Quadratic (same reason as number 2)

4. 3x² - 6x + 7 = 0
    Quadratic (same reason as number 2)

5. Linear - same reason as number 1

1.polynomial because it have a exponent of 1 2-4. Is quadratic because it have a exponent of 2 and if we change it in standard form it become a quadratic equation 5. Is not a quadratic..its a polynomial desame in no.1
