Question

a3-21a-20 solve this middle term factor

Answer 1

Answer:

a = 1 , 20

Solution:

Here,

The given polynomial is ;

a² - 21a + 20 .

We need to factorize the given polynomial using middle term splitting method.

Thus,

=> a² - 21a + 20

=> a² - 20a - a + 20

=> a(a - 20) - (a - 20)

=> (a - 20)(a - 1)

For the zeros of the given polynomial ;

=> a² - 21a + 20 = 0

=> (a - 20)(a - 1)

=> a = 1 , 20

Hence,

a = 1 , 20
