Astudent performed the following system to find the solution to the equation x2-2x-8=0

B. in step 1

Step-by-step explanation:

Given that a student performed the following steps to find the solution of the quadratic equation .

Step 1: Factor the polynomial into (x-4) and (x-2).

Step 2: x-4=0 and x-2=0

Step 3: x=4 and x=2.

Now we need to find about which step has the error.

let's multiply (x-4) and (x-2)

we get :

While original problem has -8 as the last term. So that means factors are wrong.

Hence choice B. in step 1. is correct

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

40 x 50 = 2000
