What is the solution to 2x^2 + x - 1 = 2

x = square root of -x + 3 / 2

Step-by-step explanation:

2x^2 + x - 1 = 2

add 1 to both sides

2x^2 + x = 3

subtract x from both sides

2x^2 = -x + 3

square root both sides

2x = square root of -x + 3

divide by 2

x = square root of -x + 3 / 2

Step-by-step explanation:

hello :

2x² + X - 1 = 2

2x² + X - 1 -2 = 2-2

2x² + X - 3 =0

(x-1)(2x+3) =0

x-1=0 or 2x+3 = 0

x =1 or x= -3/2

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
