Question

Use polynomial identities to multiply the expressions;
left parenthesis 12 plus 15 right parenthesis squared

The correct answer is: Hence, the answer is: 729.


    ANSWER:
    Hint:
    Let a and b be any real number, variables or multiples of the both, then we have: .
    left parenthesis a plus b right parenthesis squared equals a squared plus 2 a b plus b squared
    We are asked to use the polynomial identities to multiply the given expression.
    Step 1 of 2:
    The given expression is left parenthesis 12 plus 15 right parenthesis squared .
    Here, a equals 12 straight & b equals 15 .
    Use the identity left parenthesis a plus b right parenthesis squared equals a squared plus 2 a b plus b squared for the expression left parenthesis 12 plus 15 right parenthesis squared
    Step 2 of 2:
    Now, substitute the value in the equation left parenthesis a plus b right parenthesis squared equals a squared plus 2 a b plus b squared to get the value of left parenthesis 12 plus 15 right parenthesis squared :
    left parenthesis 12 plus 15 right parenthesis squared equals 12 squared plus 2 left parenthesis 12 right parenthesis left parenthesis 15 right parenthesis plus 15 squared.
    equals 144 plus 360 plus 225
    =729
    Hence, the answer is:729 .
    Note:
    Polynomial identities are used to reduce the time and space while you solve higher degree polynomial expressions.
