Q. Factor the expression completely.\newline16x4+40 -16 x^{4}+40 \newlineAnswer:
  1. Identify GCF: First, identify the greatest common factor (GCF) of the terms in the expression 16x4-16x^{4} and 4040. The GCF of 16-16 and 4040 is 88, and since there is no xx term in 4040, xx cannot be part of the GCF. So, we factor out 8-8 from both terms.
  2. Factor Out GCF: Now, write the expression as a product of the GCF and the remaining terms.\newline16x4+40=8(2x45)-16x^{4} + 40 = -8(2x^{4} - 5)\newlineCheck to ensure that when you distribute 8-8 back into the parentheses, you get the original expression.\newline8×2x4=16x4-8 \times 2x^{4} = -16x^{4} and 8×(5)=40-8 \times (-5) = 40, which is correct.
  3. Write as Product: Next, look inside the parentheses to see if the expression 2x452x^{4} - 5 can be factored further. Since 2x42x^{4} is a term with an even power of xx and 55 is a prime number, there are no common factors and it is not a difference of squares or any other factorable form. Therefore, the expression inside the parentheses cannot be factored further.
  4. Check Distribution: The expression is now fully factored.\newlineThe completely factored form of the expression 16x4+40-16x^{4} + 40 is 8(2x45)-8(2x^{4} - 5).
