Identify all factors of the expression 〖4x〗^2+17x-15.
Basile [38]

The factors of given expression are: -5 and 3/4

Step-by-step explanation:

Given equation is:

4x^2+17x-15

Making pairs for the mid-term 17x by factoring the product of co-efficient of 4x^2 and 15

4x^2+20x-3x-15

= 4x(x+5) - 3(x+5)

=(4x-3)(x+5)

Now

4x-3 = 0\\4x = 3\\x = \frac{3}{4}

x+5 = 0\\x = -5

Hence,

The factors of given expression are: -5 and 3/4

An Individual Retirement Account​ (IRA) has ​$17 comma 000in​ it, and the owner decides not to add any more money to the account
Umnica [9.8K]

Answer: The owner reaches at Rs. 56438.28 after 30 years.

Step-by-step explanation:

Since we have given that

Sum = Rs. 17000

Rate of compounded daily = 4%

Number of years = 30 years

So, Using "compound interest formula" we get that :

A=P(1+\dfrac{r}{n})^{nt}\\\\A=17000(1+\dfrac{0.04}{365})^{365\times 30}\\\\A=17000(1.000109589)^{10950}\\\\A=56438.28

Hence, The owner reaches at Rs. 56438.28 after 30 years.
