Frame a formula " The product of 3 consecutive numbers ( the smallest being x) is 310.
x × ( x + 1) × (x + 3) = 310
x × (x + 2) × (x + 4) = 310
x × (x + 1) × (x + 5) = 310
(x + 1) × (x + 3) × (x + 5) = 310
Frame a formula for " A number x multiplied by itself is 25 more than the number".
2x2 = 25
2x2 + x = 25
x2 = x + 25
x2 + 25 = x
In formula P = 2 (l x b ), make l the subject.
l = 2b - p/2
l = 2 -2b/p
l = p - 2/2b
l= p - 2b/2
