linda thinks of a two digit number. the sum of the digits is 8. if she reverses the digits, the new number is 26 greater than he

antoniya [11.8K]

Let
x = the 10s digit
y = the units
N1----------> original number
N2----------> new number
N2=N1+36--------- >N2-N1=36
y+x=8------------- > equation (I)
then
10x + y = N1
10y+x=N2

(10y+x)-(10x+y)=36- -----> 9y-9x=36------- > y-x=4----------- > equation (II)

resolving (I) and (II)
 y+x=8
y- x=4
-----------------
2y+0x=12--------------- >y=6
then
x=8-y=8-6=2----------> x=2

N1=26 and N2=62

the two digit number is 26

Which polynomials have 2 roots

madreJ [45]

Answer:

Option D

Step-by-step explanation:

Option A

x² - 3x² + 2x² = 0

Therefore, the given polynomial has no roots.

Option B

x² + 2x + 8

By quadratic formula,

x = $\frac{-2\pm \sqrt{4-32} }{2}$

= $\frac{-2\pm \sqrt{-28} }{2}$

Therefore, roots are imaginary and for a polynomial with degree 1 or more than 1, both the roots can't be imaginary.

So the polynomial can't have exactly two roots.

Option C

99x³ - 33x + 1

Since the polynomial is of degree 3, so it will have three roots.

Therefore, the polynomial will not have exactly 2 roots.

Option D

√2x - 3x² + 7√2

By quadratic formula,

x = $\frac{-\sqrt{2}\pm\sqrt{(\sqrt{2})^2-4(-3)(7\sqrt{2} )}}{2(-3)}$

x = $\frac{-\sqrt{2}\pm\sqrt{2+84\sqrt{2} )}}{(-6)}$

There are exactly two real roots.

Therefore Option D is the answer.

Option E

4x + 11x - 111

Since this polynomial is of a degree 1.

There will be only one root.
