What is the solution to 2x^2 + X - 1 = 2
2 answers:
Answer: 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
Answer:
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
