Find: (6m5 + 3 – m3 – 4m) – (–m5 + 2m3 – 4m + 6)

belka [17]

Given:

The expression is:

$(6m^5+3-m^3-4m)-(-m^5+2m^3-4m+6)$

To find:

The resulting polynomial in standard form.

Solution:

We have,

$(6m^5+3-m^3-4m)-(-m^5+2m^3-4m+6)$

Write subtraction of a polynomial expression as addition of the additive inverse.

$(6m^5+3-m^3-4m)+(m^5-2m^3+4m-6)$

Rewrite terms that are subtracted as addition of the opposite.

$6m^5+3+(-m^3)+(-4m)+m^5+(-2m^3)+4m+(-6)$

Group like terms.

$[6m^5+m^5]+[3+(-6)]+[(-m^3)+(-2m^3)]+[(-4m)+4m]$

Combine like terms.

$7m^5+(-3)+(-3m^3)+0$

On simplification, we get

$7m^5-3-3m^3$

Write the polynomial in standard form.

$7m^5-3m^3-3$

Therefore, the required polynomial in standard form is $7m^5-3m^3-3$ .

2x^2+3x=(2x-1)(x+1) Pls do explain

Serggg [28]

<h3>Answer:</h3>

$x=-\frac{1}{2}$

<h3>Step-by-step explanation:</h3>

You could solve this problem by either: Factoring or by using the Quadratic Formula.

SOLVING BY FACTORING STEPS

STEP 1: Move (2x−1)(x+1) to the left side of the equation by subtracting it from both sides.

$2x^2+3x-(2x-1)(x+1)=0$

STEP 2: Simplify 2x^2+3x−(2x−1)(x+1).

$2x+1=0$

STEP 3: Simplify each term.

$2x^2+3x-2x^2-x+1=0$

STEP 4: Simplify by adding terms.

$2x+1=0$

STEP 5: Subtract 1 from both sides of the equation.

$2x=-1$

STEP 6: Divide each term by 2 and simplify.

$x=-\frac{1}{2}$

SOLVE BY USING THE QUADRATIC FORMULA STEPS

STEP 1: Move all terms to the left side of the equation and simplify.

$2x+1=0$

STEP 2: Subtract 1 from both sides of the equation.

$2x=-1$

STEP 3: Divide each term by 2 and simplify.

$x=-\frac{1}{2}$
