<h2>Question:</h2>

→To simple the given equations

( 2x + 1 ) + 5x
( x + 3 ) ( x + 4 )
( x + y ) ²
( 2x + 1 ) ( x - 3 )

<h2 /><h2>Answer:</h2>

<h3>Part 1:</h3>

$\green{step \: 1}$

→ $3 ( 2x + 1 ) + 5x$

$\green{step \: 2}$

→ $6x + 3 + 5x$

$\green{step \: 3}$

→ $\blue{11x + 3✓}$

<h3>part 2:</h3>

$\green{step \: 1}$

→ $( x + 3 ) ( x + 4 )$

$\green{step \: 2}$

→ ${x}^{2} + 4x + 3x + 12$

$\green{step \: 3}$

→ $\blue{ {x}^{2} + 7x + 12✓}$

<h3>part 3:</h3>

$\green{step \: 1}$

→ $( x + y ) ^2$

$\green{step \: 2}$

→ $\blue{{x}^{2} + {y}^{2} + 2xy✓}$

<h3>part 4:</h3>

$\green{step \: 1}$

→ $( 2x + 1 ) ( x - 3 )$

$\green{step \: 2}$

→ $2 {x}^{2} - 6x + x - 3$

$\green{step \: 3}$

→ $\blue{2 {x}^{2} - 5x - 3✓}$

Please help me with the problem

mixas84 [53]

Let's see what we're working on here

$\frac{1}{2} - 2(m) =?$
? = 0
$Simplify this →$ $\frac{1}{2}$

$\frac{1}2y} - 2(m) = ?$

$\frac{2(m)(2)}{2}$

$\frac{1 - 4(m)}{2} = ?$

$\frac{1 - 4(m)}{2} = 2$

$-4(m) + 1 = 0$
Subtract ( - )the number 1 from each of your sides on this part

4(m) = 1
Multiply( ×) the number -1 to your sides for this part of the equation

Therefore, the value of m is $\frac{1}{4}$
$m = \frac{1}{4}$

HELP PLEASE 50 POINTS!!!! PLZ DON'T GUESS!

Olin [163]

Hey DatGamer13!

Question:

Solve for x

Solution:

Subtract 10 from both sides.

3x^2 + 13x − 10 = 10 − 10

3x^2 + 13x − 10 = 0

Factor left side of equation.

(3x − 2) (x + 5) = 0

Set factors equal to 0.

3x − 2 = 0 or x + 5 = 0

Answer:

x = 2/3 or x = −5
