Answer:

x=-77.5

Step-by-step explanation:

since we're looking for x,18 must cross the equal sign to become negative.

0.4x=-13-18

0.4x=-31

dividing both side by 0.4,

we have x=-31÷0.4

therefore x= -77.5

2x^2+3x=(2x-1)(x+1)<br> Pls do explain
Serggg [28]
<h3><u>Answer:</u></h3>

<u />x=-\frac{1}{2}

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

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

SOLVING BY FACTORING STEPS

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

<em />2x^2+3x-(2x-1)(x+1)=0

<em>STEP 2:</em><em> Simplify 2x^2+3x−(2x−1)(x+1).</em>

<em />2x+1=0

<em>STEP 3: </em><em>Simplify each term.</em>

<em />2x^2+3x-2x^2-x+1=0

<em>STEP 4: </em><em>Simplify by adding terms.</em>

<em />2x+1=0

<em>STEP 5:</em><em> Subtract 1 from both sides of the equation.</em>

<em />2x=-1

<em>STEP 6: </em><em>Divide each term by 2 and simplify.</em>

<em />x=-\frac{1}{2}

SOLVE BY USING THE QUADRATIC FORMULA STEPS

<em>STEP 1: </em><em>Move all terms to the left side of the equation and simplify.</em>

<em />2x+1=0<em />

<em>STEP 2: </em><em>Subtract 1 from both sides of the equation.</em>

<em />2x=-1<em />

<em>STEP 3: </em><em>Divide each term by 2 and simplify.</em>

<u />x=-\frac{1}{2}
