Q. Rewrite the expression as a product of four linear factors:(12x2+13x)2+4(12x2+13x)+3Answer:
Recognize Perfect Square Trinomial: Recognize the given expression as a perfect square trinomial. The expression given is (12x2+13x)2+4(12x2+13x)+3. This resembles the form of a perfect square trinomial a2+2ab+b2, which factors into (a+b)2.
Factor as Perfect Square: Factor the expression as a perfect square trinomial.Let's set a=(12x2+13x) and b=2, then the expression becomes a2+2ab+b2, which is a perfect square trinomial.So, the expression can be written as ((12x2+13x)+2)2.
Expand for Verification: Expand the perfect square trinomial to verify the factorization.Expanding ((12x2+13x)+2)2 gives us (12x2+13x)2+2∗(12x2+13x)∗2+22, which simplifies to (12x2+13x)2+4(12x2+13x)+4.However, we notice that the original expression has a constant term of 3, not 4. This means we made a mistake in our factorization.
