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.

The expression re-written: 3(2) - 4(3)
First, we multiply (PEMDAS)
3 * 2 = 6
4 * 3 = 12

The answer is right because 12^2 + 35^2 = 1369 and 37^2 = 1369 1369=1369 so it is a right triangle
