The solutions to the equation 2x^2+x-1=2 are x=-3/2 or x= ?

1

Step-by-step explanation:

2x^2 + x -1 = 2

2x^2 + x-1-2 = 0

2x^2 + x -3 = 0

2x^2 -2x + 3x-3 = 0

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

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

2x + 3 = 0

or x-1 = 0

x = -3/2 or 1

i think the answer is seven, for if i'm being useless °ω°

step-by-step explanation:

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
