We want to factor:
2x^4+5x^2+3

This may seem tricky because of the high powers, but remember that x^4=(x^2)^2. Then we can factor it as:
2x^4+5x^2+3=(2x^2+3)(x^2+1)

Which expressions are equivalent to 16? Select each correct expression
photoshop1234 [79]

Answer: Choose 2 to the 4th power, 4 to the 2nd power, and 16 to the power of 1

Step-by-step explanation:

When working with exponents, whatever number is the corner of another number, multiply it by itself. For instance, if you have 2 to the 4th power, multiply 2x2x2x2 which is 16. Also there is 4 to the 2nd power which is 4x4 which is also 16. Lastly you have 16 to the power of 1 and anything multiplied by 1 stays the same.
