Question

Identify the value of c that makes the trinomial factorable using the perfect square pattern.
3 x squared plus 24 x plus c

hintHint:

using condition b squared minus 4 a c equals 0  in the trinomial to find c which makes the trinomial the perfect square   Ans :- c = 48

The correct answer is: c = 48


    Given , 3 x squared minus 24 x plus c text  comparing it with  end text a x squared plus b x plus c
    Here a equals 3 semicolon b equals negative 24
    b squared minus 4 a c equals 0   if the trinomial is a perfect square.
    b squared equals 4 a c not stretchy rightwards double arrow left parenthesis negative 24 right parenthesis squared equals 4 left parenthesis 3 right parenthesis left parenthesis c right parenthesis not stretchy rightwards double arrow 576 equals 12 c

     c equals 48

    ∴ c = 48
