Unit form: 6 nines =_ nines + _ nine

Step-by-step explanation:

Unit form: 6 nines=......nines +.... nine

By this it is meant,

We can write that as

And that's true.

This is representation of distributive property.

So ,

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

the answer is two. hope this !
