Find the number of real number solutions for the equation.x2 − 2x + 9 = 0

Talja [164]

Hi there!

We can use the discriminant of the quadratic formula to find the number of real solutions to this (or any other quadratic) equation.

The discriminant can be found by plugging in the data from the equation into the following formula:
$d = {b}^{2} - 4ac \\ with \: y \: = a {x}^{2} + bx + c$

When we fill in the data from the question we get
$d = ( - 2) {}^{2} - 4 \times 1 \times 9 = 4 - 36 = - 32$

Since d < 0 the equation has zero real solutions.

Find the 50th term sequence 5 , -2 , -9 , -16

Anni [7]

5 - 7 = - 2 ;
- 2 - 7 = - 9 ;
-9 - 7 = -16 ;
"common difference" d is - 7 ;
The n-th term of an arithmetic sequence is of the form <span>an = a1 + (n – 1)d ;
</span>a50 = 5 + 49 × ( - 7 ) = 5 - 343 = - 338;
