how reversing the rules of multiplying squares of binomials would be useful to factor a perfect square trinomial
Answer to Problem 52P
Reversing the rules of multiplying squares of binomials would be useful to factor a perfect square trinomial
Explanation of Solution
Given information:
Condition of factorising a perfect square trinomial
Calculation:
Consider squaring a binomial as follows:
Or
It would be useful to reverse the rule since it is much easier to check for the first and last terms for perfect squares and middle term to be the twice product of one of the terms from first and last terms of the expression in order to factor a perfect trinomial
