Factor completely 3x^2+2x-1
Morgarella [4.7K]

Answer:

(3x - 1)(x + 1)

Step-by-step explanation:

3x^2 factors into 3x and x.

-1 factors into -1 and 1.

Now we try different positions of 3x, x, -1, and 1 until we find the correct factorization.

Try: (3x - 1)(x + 1)

When you multiply the two factors together, the middle term will be 3x - x = 2x

Since 2x is the original middle term, this is the correct factorization.

Answer: (3x - 1)(x + 1)

1.Ramu deposited Rs. 10,000 in a bank where interest is compounded
Ivahew [28]

Answer:

Future value, A = $10,500

Step-by-step explanation:

<u>Given the following data;</u>

Principal = Rs. 10,000

Interest rate compounded half yearly = 10% = 10/2 = 5%

Time = 1 year

To find the future value, we would use the compound interest formula;

A = P(1 + \frac{r}{100})^{t}

Where;

  • A is the future value.
  • P is the principal or starting amount.
  • r is annual interest rate.
  • n is the number of times the interest is compounded in a year.
  • t is the number of years for the compound interest.

Substituting into the equation, we have;

A = 10000(1 + \frac{5}{100})^{1}

A = 10000(1 + 0.05)

A = 10000(1.05)

<em>Future value, A = $10,500</em>
