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

Mathematics
1 answer:
maxonik [38]3 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

Can u please help me with 27
Pachacha [2.7K]
The answer would be 237.375. To get this answer, you will first use the formula given for each unit. First, you will do the first unit by putting 8 to the third power, or basically 8x8x8. After you get the product 512, you will then do the next unit. Do that one by doing 6.5 to the third power, or as followed, 6.5x6.5x6.5. Once you get the product 274.625, you will then subtract that from 512. You will then receive the answer 237.375.
