I need help to reduce these numbers i need help please
valina [46]
All you have to do is understand what fraction it is and reduce it. So first you have to figure out what the word reduce means and the word means another to figuring it out in its lowest terms and for example, your fraction 2/24 can be reduced in its simplest terms 1/12 and the way i did that was that i'd had to divide both the numerator and denominator by 2 because I know that both the numerator and denominator are divisible by 2 and so if you divide you get 1/16 and that's how you reduce fractions and so follow this procedure and you'll get everything correct.

(2x^3+9x^2+x-12)/(x+4) simplify
neonofarm [45]

Answer:

<h2>2 {x}^{2}  + x - 3</h2>

Step-by-step explanation:

\frac{2 {x}^{3}  + 9 {x}^{2}  + x - 12}{x + 4}

Write 9 {x}^{2} as a sum

\frac{2 {x}^{3}  - 2 {x}^{2} + 11 {x}^{2}   + x - 12}{x + 4}

Write X as a sum

\frac{2 {x}^{3}  - 2 {x}^{2} + 11 {x}^{2} - 11x + 12x - 12  }{x + 4}

Factor out 2 {x}^{2} from the expression

\frac{2 {x}^{2}(x - 1) + 11 {x}^{2} -  11x + 12x - 12  }{x  + 4}

Factor out 11x from the expression

\frac{2 {x}^{2} (x - 1) + 11x(x - 1) + 12x - 12}{x + 4}

Factor out 12 from the expression

\frac{2 {x}^{2}(x - 1) + 11(x - 1)  + 12(x - 1) }{x + 4}

Factor out X - 1 from the expression

\frac{(x - 1)(2  {x}^{2}   + 11x + 12)}{x + 4}

Write 11x as a sum

\frac{(x - 1)(2 {x}^{2}  + 8x + 3x + 12)}{x + 4}

Factor out 2x from the expression

\frac{(x - 1)(2x(x + 4) + 3x + 12)}{x + 4}

Factor out 3 from the expression

\frac{(x - 1)(2x(x + 4) + 3(x  + 4)}{x + 4}

Factor out X + 4 from the expression

\frac{(x - 1)(x + 4)(2x + 3)}{x + 4}

Reduce the fraction with X + 4

(x - 1)(2x + 3)

Multiply the parantheses

2 {x}^{2}  + 3x - 2x - 3

Collect like terms

2 {x}^{2}  + x - 3

Hope this helps...

Good luck on your assignment...
