Match each equation with its solution set. Tiles a2 - 9a + 14 = 0 a2 + 9a + 14 = 0 a2 + 3a - 10 = 0 a2 + 5a - 14 = 0 a2 - 5a - 14 = 0 Pairs {-2, 7} {2, - 7} {-2, - 7} {7, 2}

For this case we will solve the equations step by step:

a2 - 9a + 14 = 0

(a-7) * (a-2) = 0

a1 = 7

a2 = 2

{7, 2}

a2 + 9a + 14 = 0

(a + 7) * (a + 2) = 0

a1 = - 7

a2 = - 2

{-2, - 7}

a2 + 5a - 14 = 0

(a + 7) * (a-2) = 0

a1 = - 7

a2 = 2

{2, - 7}

a2 - 5a - 14 = 0

(a-7) * (a + 2) = 0

a1 = 7

a2 = - 2

{-2, 7}
