Answer:

Linear expression

Step-by-step explanation:

First, simplify the expression.

Given expression: 9p-10q+3-9p

Collect like terms:   9p-9p-10q+3

Combine like terms:   -10q+3

As each term of the expression is either a numeric constant or a variable with no exponent, this is a <u>linear expression</u>.

It can also be called a <u>binomial expression</u> since the expression only contains two terms (the constant and the variable).

Find the discrimanant and the number of real roots for this equation 9x^2+12x+4=0
castortr0y [4]

For this case we have that by definition, the discriminant of a quadratic equation ax ^ 2 + bx + c = 0, is given by:

d = b ^ 2-4 (a) (c)

d> 0: Two different real roots

d = 0: Two equal real roots

d: Two different complex roots

If we have 9x ^ 2 + 12x + 4 = 0, then:

a = 9\\b = 12\\c = 4

Substituting the values:

d = 12 ^ 2-4 (9) (4)\\d = 144-144\\d = 0

Thus, we have two equal real roots.

ANswer:

We have two equal real roots.

Does an equation always have a solution? Could you come up w/ an equation that does not have a solution? If yes, explain why thi
Damm [24]
An equation does not always have a solution. Sometimes, an equation can have a variable that does not equal the remaining value on the other side. For example, root negative x could never equal a number squared.
√-x ≠ 14²
This equation cannot have a solution because you can't square any number to get a negative solution. Therefore, x= no solution.
