Answer:

Student is incorrect

Step-by-step explanation:

x^2-7x+10=0

x^2+2x-5x+10=0

x(x-2)-5(x-2)=0

(x-5)(x-2)=0

x-5=0    ,     x-2=0

x=5     ,       x=2

So the correct solutions  of given equation is 2 and 5

In the solution of the equation 5 + 3x = -2x + 9, 2 x is added to the equation first. which of the following should be done next
wariber [46]

Hi!

<h3>Let's do the first step (add 2x). </h3>

5 + 3x + 2x = -2x + 2x + 9

<em>5 + 5x = 9</em>

<h3>Our goal is to isolate x on one side, so the next step would be to subtract 5 (or add -5).</h3>

5 + -5 + 5x = 9 + -5

<u><em>5x = 4</em></u>

<h2>The answer is B. add -5</h2><h3><em>And if you want to finish solving, you would divide by 5 on both sides.</em></h3>

5x/5 = 4/5

x = 0.8

Hope this helps! :)
