Factor this <br> -4x²y²y²+4x³y³

Katena32 [7]

Factoring the term $-4x^2y^2y^2+4x^3y^3$ we get $-4x^2y^3(y-x)\\$

Step-by-step explanation:

We need to factor the term: $-4x^2y^2y^2+4x^3y^3$

For factoring we need to find the common term in the expression given.

Solving:

$-4x^2y^2y^2+4x^3y^3\\=-4x^2y^4+4x^3y^3\\=-4x^2y^3(y-x)\\$

It cannot be simplified further.

So, Factoring the term $-4x^2y^2y^2+4x^3y^3$ we get $-4x^2y^3(y-x)\\$

Solve the radical equation the square root of 8x+9=x+2, how would you start it?

kobusy [5.1K]

Answer: I will start it by squaring both sides of the equation.

The solution is x = 5 or x=-1

Step-by-step explanation:

$\sqrt{8x+9} =x+2$ Square the left and right sides. The square root of 8x+9 squared is 8x+9 and the x+2 squared is x^2 + 4x +4. We will now have the new equation,

8x + 9 = $x^{2}$ + 4x + 4 now set them equal zero first sutract x^2 from both sides

-x^2 -x^2

-x^2 + 8x + 9 = 4x +4 subtract 4x from both sides

-4x -4x

-x^2 +4x + 9 = 4 Finally subtract 4 from both sides

-4 -4

-x^2 + 4x +5 = 0 Remember the largest degree has a negative coefficient so divide them all by -1.

x^2 - 4x -5 = 0 Now find two numbers that their product is -5 and their sum is -4. the numbers 1 and -5 works out.

Now rewrite the whole equation as,

x^2+ 1x -5x -5=0 Factor by grouping on the left side

x(x+1) -5(x+1)= 0 Factor out x+1

(x+1)(x-5) = 0 Now apply the zero product

x+1 = 0 or x-5 = 0

-1 -1 +5 +5

x = -1 or x = 5
