Question

25 m square + 30 M + 9​

Answer 1

Step-by-step explanation:

25 m ^2 = 625 +30 =655 +9 = 664

Answer 2

Answer:

Step-by-step explanation:

25m^2+30m+9=0

Here, a=25, b=30 and c=9

Discriminant=√b^2-4ac

D=√(25)^2-4×25×9

D=√625-900

D=√-275<0

Discriminant is smaller than 0 so the equation hasn't any roots...
