Answer 2

Answer:

Solution :-

✭ 7m² + 28m - 224 = 0

➜ 7(m² + 4m - 32) = 0

➜ 7{m² + (8 - 4)m - 32} = 0

➜ 7{m² + 8m - 4m - 32} = 0

➜ 7{m(m + 8) - 4(m + 8)} = 0

➜ 7{(m + 8) (m - 4)} = 0

➜ 7(m + 8) (m - 4) = 0

➜ (m + 8) = 0

➜ m + 8 = 0

➜ m = - 8

Either,

➜ (m - 4) = 0

➜ m - 4 = 0

➜ m = 4

∴ The answer of this question is 4, - 8
