Simplify fully: X^2+3x-4/ 2x^2-5x+3

sweet-ann [11.9K]

Answer:

(-x - 3) • (x - 1)

Step-by-step explanation:

Step 1 :

2

Simplify —

1

Equation at the end of step 1 :

((((x2)+3x)-(2•x2))-5x)+3

Step 2 :

Equation at the end of step 2 :

((((x2) + 3x) - 2x2) - 5x) + 3

Step 3 :

Step 4 :

Pulling out like terms :

4.1 Pull out like factors :

-x2 - 2x + 3 = -1 • (x2 + 2x - 3)

Trying to factor by splitting the middle term

4.2 Factoring x2 + 2x - 3

The first term is, x2 its coefficient is 1 .

The middle term is, +2x its coefficient is 2 .

The last term, "the constant", is -3

Step-1 : Multiply the coefficient of the first term by the constant 1 • -3 = -3

Step-2 : Find two factors of -3 whose sum equals the coefficient of the middle term, which is 2 .

-3 + 1 = -2

-1 + 3 = 2 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -1 and 3

x2 - 1x + 3x - 3

Step-4 : Add up the first 2 terms, pulling out like factors :

x • (x-1)

Add up the last 2 terms, pulling out common factors :

3 • (x-1)

Step-5 : Add up the four terms of step 4 :

(x+3) • (x-1)

Which is the desired factorization

Final result :

(-x - 3) • (x - 1)

REASONING If the solution set of a polynomial inequality is (−3, 3), what will be the solution set if the inequality symbol is r

Arte-miy333 [17]

Answer: The new solution set is $(-\infty,-3)\cup(3,\infty).$

Step-by-step explanation: Given that the solution set of a polynomial inequality is (-3, 3).

We are to find the solution set if the inequality symbol is reversed.

Let x denotes the unknown variable in the original inequality.

Then, according to the given information, we can write

$x\in (-3,3)\\\\\Rightarrow -3$

Now, if we reverse the sign of the inequality, then the value of x will be

$x3.$

This new solution set can be written as

$x\in(-\infty,-3)\cup(3,\infty).$

Thus, the new solution set is $(-\infty,-3)\cup(3,\infty).$
