Question

if (m+n) =6 and mn 11/4 find 3m2 - 3n2​

Answer 1

Step-by-step explanation:

if if m + n is equal to 6 and m n is equal to 11 /4 when first will do the whole square of M that is m square + 10 square + 2 ml is equal to 6 whole square that is 36 put the formula in its place it is m square + n square plus 11 by 4 into 6 that is a m square + n square + 22 by 3 is equal to 36 now you will take 22 by 3 to the right side means m square + and square is equal to 36 - 22 by 3 that is m square plus n square is equal to 86/3 now you will divide 86 by 3 so you will get them something like 24 2 by 3 now you will multiply the value of m square + 10 square 5 by 3 so you will get 3 m square + 3 square is equal to 24 2 by 3 into 3 that is 24 by to that is 12 so your answer is 12
