Which statement is true for the function
x² + 13x + 22

• The zeroes are -2 and -11 because the factors are (x + 2)(x + 11)
• The zeroes are -2 and 11 because the factors are (x + 2)(x - 11)
• The zeroes are 2 and -11 because the factors are (x - 2)(x + 11)
• The zeroes are 2 and 11 because the factors are (x - 2)(x - 11)

Which statement is true for the function
x² + 4x - 45

• The zeroes are -5 and -9 because the factors are (x + 5)(x +9)
• The zeroes are -5 and 9 because the factors are (x + 5)(x - 9)
• The zeroes are 5 and -9 because the factors are (x - 5)(x + 9)
• The zeroes are 5 and 9 because the factors are (x - 5)(x - 9)

So if  (2x + 7)(3x + 4) then the zeroes are...

• 7/2 and 4/3
• 7/2 and -4/3
• -7/2 and 4/3
• -7/2 and -4/3

Which statement is true for the function
3x² + 10x - 8

• The zeroes are -⅔ and -4 because the factors are (3x + 2)(x + 4)
• The zeroes are -⅔ and 4 because the factors are (3x + 2)(x - 4)
• The zeroes are ⅔ and -4 because the factors are (3x - 2)(x + 4)
• The zeroes are ⅔ and 4 because the factors are (3x - 2)(x - 4)
