Factor each polynomial x^2-9x+10 <br> Show your work

jok3333 [9.3K]

Answer:

not factorable

Step-by-step explanation:

$x^{2} - 9x +10\\$

The easiest way to factor is to find two numbers of the "a" value (the coefficient before $x^{2}$ ) and the factors of the c value (10) that ADD up to give you -9, in this case it would be:

1 -10 --> 1(-10) gives you -10

1 -1 --> 1(-1) gives you -1

adding these together -10 + (-1) = -11 which does not equal -9.

You could stop here and conclude that this is not factorable by inspection.

Another method: using the quadratic formula to find its roots.

Roots: $(\frac{9-\sqrt{41} }{2}, 0)$ and $(\frac{9+\sqrt{41}}{2}, 0)$

Natasha_Volkova [10]

Answer: the credit union loaned out $40000 at 6% and $10000 at 12%

Step-by-step explanation:

Let x represent the amount that the

credit union loaned out at the annual rate of 6%.

Let y represent the amount that the

credit union loaned out at the annual rate of 12%.

credit union loaned out $50,000, part at an annual rate of 6% and the rest at an annual rate of 12%. It means that

x + y = 50000

The interest on $x after 1 year would be

6/100 × x = 0.06x

The interest on $y after 1 year would be

12/100 × y = 0.12y

The collected combined interest was $3,600 that year. It means that

0.06x + 0.12y = 3600- - - - - - - - - 1

Substituting x = 50000 - y into equation 1, it becomes

0.06(50000 - y) + 0.12y = 3600

3000 - 0.06y + 0.12y = 3600

- 0.06y + 0.12y = 3600 - 3000

0.06y = 600

y = 600/0.06

y = $10000

x = 50000 - y = 50000 - 10000

x = $40000
