Answer 1

Answer:

First plz mark me as a brainlist...

Step-by-step explanation:

a^ 2¢== X ki power-5

+3=-7

The correct is 7+5= 12

Answer 2

Answer:

The factories form is a^2-3a-40=(a-8)(a+5)a

2

−3a−40=(a−8)(a+5)

Step-by-step explanation:

Given : Polynomial a^2-3a-40a

2

−3a−40 .

To find : Factories the polynomial ?

Solution :

Polynomial a^2-3a-40a

2

−3a−40 .

Applying middle term split,

a^2-3a-40=a^2-8a+5a-40a

2

−3a−40=a

2

−8a+5a−40

a^2-3a-40=a(a-8)+5(a-8)a

2

−3a−40=a(a−8)+5(a−8)

a^2-3a-40=(a-8)(a+5)a

2

−3a−40=(a−8)(a+5)

The factories form is a^2-3a-40=(a-8)(a+5)a

2

−3a−40=(a−8)(a+5) .
