Question

Match the trinomials with their factors. Tiles a2 + a − 20 a2 − 9a + 20 a2 − 8a − 20 a2 − 12a + 20 a2 − 19a − 20 Pairs Factors Trinomials (a − 4)(a − 5) arrowBoth (a − 10)(a − 2) arrowBoth (a − 4)(a + 5) arrowBoth (a − 10)(a + 2) arrowBoth

Answer 1

For this case we have to factorize the following trinomials as the product of two binomials.
 We have then:
 a2 + a - 20
 (a + 5) (a-4)

 a2 - 9a + 20
 (a-5) (a-4)

 a2 - 8a - 20
 (a-10) (a + 2)

 a2 - 12a + 20
 (a-10) (a-2)

 a2 - 19a - 20
 (a-20) (a + 1)
