The solution to the equation 2x^2+x-1=2

Mathematics
1 answer:
maxonik [38]2 years ago
5 0

Answer:

x=-\frac{3}{2}, x=1

Step-by-step explanation:

2x^2+x-1=2

Subtract 2 from both sides and factor:

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

Solve each factor individually:

2x+3=0\\2x=-3\\x=-\frac{3}{2}

x-1=0\\x=1
