An equation is shown. 2x2 - 5x - 3 = 0 What values of x make the equation true?

1.4=x

Step-by-step explanation:

4-5x-3=0

7-5x=0

+5x   +5x

-

7=0+5x

-0   -0

7=5x

÷5   ÷5

-

1.4=x

Hope this helps ;D

B). additive identity

Step-by-step explanation:

Given statement is "If -11 + N=-11, then N is" the

Now we need to find the matching property from the given choices:

A). additive inverse

B). additive identity

C).  multiplicative inverse

D). multiplicative identity​

we can see that given equation -11 + N = -11 contains -11 on both sides.

That means there is no effect of adding "N"

Which is definition of Additive identity.

So the correct choice is : B). additive identity
