Question

Factor the polynomial 3x4 – 2x2 + 15x2 - 10 by grouping.
Which product is the factored form of the polynomial?
(x2 - 5)(3x2 + 2)
O (22 – 2)(3x2 + 5)
(22 + 5)(3x2 – 2)
0 (372 - 5)(2+2)

Answer 1

Answer:

see explanation

Step-by-step explanation:

Given

3$x^{4}$ - 2x² + 15x² - 10

Factor the first/second and third/fourth terms )

= x²(3x² - 2) + 5(3x² - 2) ← factor out (3x² - 2) from each term

= (3x² - 2)(x² + 5)

Answer 2

Answer: (3x² - 2)(x² + 5)
