Will mark brainliest!! solve & simplify the following equation: 2x²-7x=4​
Goryan [66]

Answer:

x=  −1 /2   or x=4

Step-by-step explanation:

This is ALGEBRA, equations, factoring and zero property. ok.. let's solve this step-by-step

2x^2−7x=4

<u>Step 1: Subtract 4 from both sides. </u>

2x^2−7x<u>−4 </u>=4 <u>−4 </u>

2x^2−7x−4=0

<u>Step 2: Factor left side of equation. </u>

(2x+1)(x−4)=0

<u>Step 3: Set factors equal to 0. </u>

2x+1=0 or x−4=0

x=  −1 /2   or x=4

(BTW, there are supposed to be two answers, it's factoring)

Sorry if the format is not clear, but I hope this helped (really feel you, algebra can be brain-striking)!! Please leave a comment, rating and/or mark as the brainliest-whichever you think I deserve! Thank You :)

I'll give brainliest!! Also 40 points!
ki77a [65]

Well, if you have a word problem for example:

Maria has 24 backpacks and 12 textbooks. She needs to fit all the books in the backpacks evenly. How will she do that?

So you could do 24 ÷ 12 = 2 textbooks per backpack OR

Add 12 together until you get to 24, 12 + 12 = 24

So all you need to do is show your work and how you solved both solutions to any type of problem. (Hope this was helpful!)
