Factoring Four Terms Grouping Polynomials

Factor Completely:

2n³ + 7n² - 2n - 7

• cannot be factored

• (n - 1)²(2n + 7)

• (n² - 1)(2n + 7)

• (n + 1)(n - 1)(2n + 7)

Factor completely:
2x³ + 5x² - 8x - 20

• (x² - 4)(2x + 5)

• (2x - 5)(x² + 4)

• (2x² - 4)(x + 5)

• (x - 2)(x + 2)(2x + 5)

Factor Completely:
3x⁴ + 3x³ - 12x² - 12x

• 3x(x³ + x²- 4x - 4)

• 3x(x²-4)(x+1)

• 3x(x+2)(x-2)(x+1)

• 3x(x²+4)(x-1)

When using factor by grouping, how many terms must we have?

• Four or more

• Two

• Three

• Doesn't matter
