Answer:

-225g^2-3g+9g^{1.6}+81g^{0.6}

Step-by-step explanation:

=-6g+9g^{0.6}\left(g+9\right)-\left(-3g\right)-15^2g^2

15^2=225

=-6g+9g^{0.6}\left(g+9\right)+3g-225g^2

-6g+9g^{1.6}+81g^{0.6}+g\cdot \:3-g^2\cdot \:225

-225g^2-3g+9g^{1.6}+81g^{0.6}

FACTOR....<br>x^2 + 10× - 2400 = 0​
Vikki [24]

Answer:

x= -5 + 5\sqrt{97}, x= -5 - 5\sqrt{97}

Step-by-step explanation:

Since this quadratic is set to zero, we can use the quadratic formula to solve this.

x^2 + 10x - 2400 = 0​

Quadractic formula =  x= -b +- \sqrt{b^2 - 4ac} /2a

For this equation:

a= 1, b=10, c=-2400

Plug these numbers into the equation and solve.

x= -10 +- \sqrt{10^2 - 4(1)(-2400})/2(1)

x= -10 +- \sqrt{100 + 9,600}/2

x= -10 +- \sqrt{9,700}/2

x= -10 +- \sqrt{2^2 * 5^2 * 97}/2

x= -10 +- 5 * 2\sqrt{97}/2

x= -10 +- 10\sqrt{97} / 2

Divide by 2.

x= -5 +- 5\sqrt{97}

Answer:

x= -5 + 5\sqrt{97} or x= -5 - 5\sqrt{97}

Answer:

Step-by-step explanation:

5x+20 = 0

5X= -20

X= -20/5 = -4

8(4n+3) = 32n+24 =0

32n = -24

n = -24/32 = -3/4

12n-6=0

12n =6

n = 6/12 = 1/2

9(2x+9)

18x+81 =0

18x= -81

x= -81/18 = -9/2= -4.5

36+9y=0

36=-9y

36/-9 = y = -4

7(n-3) = 0

7n-21=0

7n = 21

n = 21/7

n=3

21+15a = 0

21= -15a

a= 21/-15 = 7/-5 = -1.4

32x-12x=0

20x=0

x=0/20 = 0

n-4-9=0

n-13=0

n=13

-3x-9+15x=0

-3x+15x-9 =0

12x-9=0

12x=9

x=9/12 = 3/4 = 0.75

-16N-14N=0

-30n=0

n=0/-30 =0

-10-90x-6x-10x²-2

-10-2-96x-10x²

-12-96x-10x²

10x²+96x+12

x= -b±√b²-4(a)(c)/2a

   {-96±√96²-4(10)(12)}/2(10)

{-96±√(9216-480)}/20

-96±√8736/20

-96±(93.4665715644)/20

-96+93.4665715644/20        -96-93.4665715644/20

-2.5334284356/20                 -189.466571564/20

-0.12667142178≅ -0.13             -9.4733285782≅ -9.47

-0.13                                                -9.47

-5(9n+9) =0

-45n-45 =0

-45n = 45

n = 45/-45 =-1

-5n+3(6+7n)

-5n+18+21n=0

-5n+21n+18 =0

16n+18 =0

16n = -18

n = -18/16 = -9/8 = -1.125

-4+7(1-3n)=0

-4+7-21n=0

3-21n=0

3=21n

3/21=n = 1/7

3n-(2n-8)

3n-2n+8=0

n+8=0

n=-8
