Which expression is equivalent to 36y^2 - 42?

Answer 1

To find an expression that is equivalent to \( 36y^2 - 42 \), we can factor the expression.

First, we can factor out the greatest common factor (GCF) of the terms. The GCF of \( 36y^2 \) and \( -42 \) is \( 6 \).

Now, we can factor \( 6 \) out:

\[ 36y^2 - 42 = 6(6y^2 - 7) \]

Thus, an equivalent expression is:

\[ 6(6y^2 - 7) \]
