Factors of Quadratics

Which statement is true for the function
5x² - 28x + 15

• The zeroes are -⅗ and -5 because the factors are (5x + 3)(x + 5)

• The zeroes are -⅗ and 5 because the factors are (5x + 3)(x - 5)

• The zeroes are ⅗ and -5 because the factors are (5x - 3)(x + 5)

• The zeroes are ⅗ and 5 because the factors are (5x - 3)(x - 5)

Which statement is true for the function
8x² - 2x - 1

• The zeroes are -¼ and -½ because the factors are (4x + 1)(2x + 1)

• The zeroes are -¼ and ½ because the factors are (4x + 1)(2x - 1)

• The zeroes are ¼ and -½ because the factors are (4x - 1)(2x + 1)

• The zeroes are ¼ and ½ because the factors are (4x - 1)(2x - 1)
