Answer:

4x³ - 4x² - 4x -8  

Step-by-step explanation:

It is given that,

4x³ - 12x² - 5 -(-8x² + 4x + 3) -----(1)

This expression shows the subtraction of two algebraic expression.

Let eq(1) 4x³ - 12x² - 5 -(-8x² + 4x + 3)

⇒4x³ - 12x² - 5 +8x² - 4x - 3  (open bracket)

= 4x³ - 12x² + 8x² - 4x -5 -3  (write similar terms together)

= 4x³ - 4x² - 4x -8  

Therefore the difference of 4x³ - 12x² - 5 -(-8x² + 4x + 3) is given by,

4x³ - 4x² - 4x -8

Answer:

4x³-4x²-4x-8

Step-by-step explanation:

We have given an expression.

(4x³-12x²-5) - (-8x²+4x+3)

We have to simplify above expression.

Open parentheses and distribute negative sign on second parentheses.

4x³-12x²-5+8x²-4x-3

Collect like terms

4x³-12x²+8x²-4x-5-3

Add the coefficients of x² and constant

4x³+(-12+8)x²-4x+(-5-3)

Simplify

4x³+(-4)x²-4x+(-8)

4x³-4x²-4x-8 which is the answer.

Q = m-a/x (solve for m)​
DaniilM [7]

Answer:

m=a/x+Q

Step-by-step explanation:

Q=m-a/x

To solve this we need to isolate m so we will bring -a/x to the other side of the equal sign so it will become positive i.e. ax now will be  written as a/x+Q=m

in other wards m=a/x+Q
