Simplify the following expression.
expeople1 [14]

Answer: 3x^{2}-24x


Step-by-step explanation:

 1. To simplify the expression given in the problem, you must apply a property of exponents called Quotient of powers, which states that when you divide two powers that have the same base, you must subtract the exponents.

2. Keeping this property on mind you have, you can rewrite the expression as following and simplify:

 \frac{-12x^{4}}{-4x}+\frac{96x^{2}}{-4x}=3x^{2}-24x

Solve this expression 5x^2-13x-6
torisob [31]

Answer:

x= -2/5 and x= 3

Step-by-step explanation:

Given equation is,

5x^2 -  13x -  6  = 0

Or, 5x^2 -  15x + 2x -  6  = 0 ( using middle term method)

Or, 5x( x- 3) + 2 (x-3) = 0

Or, (x-3) (5x+2) = 0

Now, x will have 2 answers because it's degree is 2. Total number of values depends on the power of variable.

So, x= 3 or, 5x = -2

             Or, x= -2/5

So, the answer is  x= -2/5 and x= 3.

1. 3x + 6y = 3 and 7x + 3y = 7<br>ons for bo​
sweet-ann [11.9K]

Answer:

(1,0)

Step-by-step explanation:

3x + 6y = 3

7x + 3y = 7

Multiply the second equation by -2

-2( 7x + 3y = 7)

-14x -6y = -14

Add this to the first equation to eliminate y

3x + 6y = 3

-14x -6y = -14

--------------------

-11 x = -11

Divide by -11

x = 1

Now find y

3x + 6y = 3

3 +6y = 3

Subtract 3 from each side

6y = 0

y =0
