notice that 27, 90 and 75 are all divisible by 3 so we can write 3(9x^4 - 30x^2 + 25) now you can try to factor whats in parentheses
we must now look for 4 numbers which are factors of 9 and 25 which give us a product of 25 and when multiplied and added give us the middle number -30 to give factors of the form (ax^2 + b)(cx^2 + d)
