Question

Factor the given expression.
x squared minus 64

hintHint:

using the formula a squared minus b squared equals left parenthesis a minus b right parenthesis left parenthesis a plus b right parenthesis  factorize the given expression

The correct answer is: ( x - 8) ( x + 8) is the factorized form of the given expression.


    ANS :-  (x-8)(x+8) is the factorized form of the given expression.
    Given x squared minus 64
    Using square root and squaring on 64 . we get left parenthesis x right parenthesis squared minus left parenthesis square root of 64 right parenthesis squared
    using the formula a squared minus b squared equals left parenthesis a minus b right parenthesis left parenthesis a plus b right parenthesis
    Here a equals x text  and  end text b equals square root of 64 equals 8

    Thenx squared minus 64 equals left parenthesis x minus 8 right parenthesis left parenthesis x plus 8 right parenthesis
    ∴ ( x - 8) (x + 8) is the factorized form of the given expression.
