We can use completing the square.We add 16 and subtract 7 to both sides. Now we get m^2+8m+16=9. The left sides becomes (m+4)^2=9. Taking the square root of both sides and subtracting 4 we get -1 and -7.

Correct option is C. He has 225 acres of land .
Let the Number of acres of land Roy have = x
As he planted corn on 1/5 of his land,
Number of acres of his land planted with corn = 1/5 × Number of acres of land Roy have
= x/5
As he planted 45 acres of his land with corn,
⇒ x/5
= 45
⇒x = 45 × 5
⇒x = 225
Therefore, number of acres of land Roy have is 225 .
