Identify Common Factor: Identify the common factor in the polynomial.The polynomial 3h8+35h4t4−12t8 does not have a common factor across all terms, so we cannot factor out a common factor from all three terms.
Recognize Quadratic Form: Recognize the polynomial as a quadratic in form. The polynomial can be seen as a quadratic in terms of h4 where h4 is the variable and t4 is the constant. The polynomial then takes the form of Ah42+Bh4C+Ct42, where A=3, B=35, and C=−12.
Factor as Quadratic: Factor the polynomial as if it were a quadratic.We will use the factoring method for a quadratic equation of the form ax2+bx+c. We need to find two numbers that multiply to A∗C (3∗−12=−36) and add up to B (35). These two numbers are 36 and −1.
Write as Binomials: Write the polynomial as two binomials.We can now express the polynomial as (3h4−1)(h4+36t4). However, this step contains a math error because the numbers 36 and −1 do not multiply to −36 and add up to 35. This is incorrect, and we need to find the correct pair of numbers.
