Question

What is the product of (-a + 3)(a + 4)?

Answer 1

The answer is :

-a^2-a+12

Explanation:

-a(a) is -a

-a(4) is -4a

3(a) is 3a

3(4) is 12

So,

-a^2-4a+3a+12

Simplify

-4a+3a is -a bcz -4+3 is -1

Final answer

a^2-a+12

Answer 2

-a^2 -a + 12

Explanation:

You have to multiply all four together.

-a times a = -a^2

-a times 4 = -4a

3 times a = 3a

3 times 4 = 12

Add them all together =

-a^2 - a + 12
