Answers
The expression is equivalent to x^4 - 12x^2 + 36 is (x^2 - 6)(x^2 - 6) correct.
We have given that
x^4 - 12x^2 + 36
We have to determine
Which expression is equivalent to x^4 - 12x^2 + 36.
What is the equivalent expression?
Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s).
(x^2 plus or minus 6)(x^2 plus or minus 6)
an easy way to do this is to only look at plus or minus 6
x^4 - 12x^2 + 36 (-12 and 36)
6 x 6 = 36
6 + 6 ≠ -12
(x^2 + 6)(x^2 + 6) is incorrect
6 x -6 ≠ 36
6 + -6 ≠ -12
(x^2 - 6)(x^2 + 6) is incorrect
-6 x -6 = 36
-6 + -6 = -12
Therefore the option (x^2 - 6)(x^2 - 6) is correct
The expression is equivalent to x^4 - 12x^2 + 36 is (x^2 - 6)(x^2 - 6) correct.
