(5m+3)^2

Step-by-step explanation:

25m²+30m+9

25m²+15m+15m+9

5m(5m+3) + 3(5m+3)

(5m+3) (5m+3)

(5m+3)^2

Answer 2

Step-by-step explanation:

25msq + 15m + 15m + 9

first two and last two numbers

5m(5m + 3) + 3(5m + 3)

(5m + 3) (5m + 3)

5m + 3 = 0 & 5m + 3 = 0

5m = -3 & 5m = -3

m = -3/5 & m = -3/5

m = -3/5
