Answer:

\dfrac{3x+4}{2x-2}

Step-by-step explanation:

Invert and multiply the way you would any fraction division problem. Then cancel common factors from numerator and denominator.

\displaystyle\frac{\left(\frac{4x^2+2x}{x^2+x-2}\right)}{\left(\frac{8x^2+4x}{3x^2+10x+8}\right)}=\frac{4x^2+2x}{x^2+x-2}\cdot\frac{3x^2+10x+8}{8x^2+4x}\\\\=\frac{2x(2x+1)(3x+4)(x+2)}{4x(2x+1)(x-1)(x+2)}=\frac{3x+4}{2(x-1)}\\\\=\frac{3x+4}{2x-2}

4−(3x−8)=21 solve this pls​
riadik2000 [5.3K]

Answer:

4 - ( 3x - 8 ) = 21

break the bracket first ,it gives : 4 - 3x + 8 = 21

12 - 3x = 21

- 3x = 21 - 12

- 3x = 9

-x = 9/3

-x = 3

X = - 3

[ check if the answer is correct, put -3 instead of X in the above equation ! we get 4 - { 3(-3) - 8 } = 21

4 - { - 9 - 8 } = 21

4 - { - 17 } = 21

break the bracket, minus and minus will multiply and will become plus , so we have 4 + 17 = 21 , hence 21 = 21 ! therefore X = -3
