Question

Now I know!
We can verify the formulae by substituting a and b with any numbers
Thus, if a -5, b = 3, then
(a - by 6-34-2-4
(a + b) = (5 + 3) = 82 - 64
- 2ab + 55-2-5-3-
a + 2ab + b = 5 + 2 * 5 * 3 + 32
- 25 - 30 +9=4
25 + 30 + 9 = 64
Use the given values to verify the formulae for squares of binomials.
(i) a = - 7. b = 8 (ii) a = 11, b = 3 ii) a = 2.5.b = 12​
