Answer:
(x^2 - 4)(x^2 - 3)
Step-by-step explanation:
Let y equal to x^2. We can rewrite the expression as:
y^2 - 7y + 12
Now, we have to look for numbers that have a product of 12 and a sum of -7. These numbers are -3 and -4. We can factor the equation:
(y - 4)(y - 3)
Now, we can substitute x^2 back in(we defined y as x^2 before):
(x^2 - 4)(x^2 - 3)
