Please help me solve a math problem in junior high school, The teacher wrote three formulas on the blackboard: the square of 5-3 = 8 * 2; the square of 9-7 = 8 * 4; the square of 15-13 = 8 * 7. Wang Hua then wrote two formulas with the same rule: the square of 11-5 = 8 * 12, and the square of 15-7 = 8 * 22. Q: let m and n be integers. Please use the formula containing m and N to reflect the above rule

m²-n²=（m+n）×（m-n）=8×（m+n）×（m-n）/8
