Formula : (a+b)(ab) = a^{2}b^{2}
Example:
Find the product (3x+2y)(3x2y).
Solution:
Clearly the given expression is in the form of (a+b)(ab) with 3x for a and
2y for b.
Therefore, (3x+2y)(3x2y) = (3x)^{2}(2y)^{2}
= 9x^{2}4y^{2}
Example:
Find the product (t+5)(t5).
Solution:
(t)^{2}(5)^{2}
= t^{2}25
