What are the zeros of the quadratic function f(x) = 2x2 – 10x – 3?

Ipatiy [6.2K]

Answer:

$x = \frac{ 5 \ + \ \sqrt{31}}{2} \ , \ x = \frac{ 5 \ - \ \sqrt{31}}{2}$

Step-by-step explanation:

$2x^2 - 10x - 3 = 0 \\\\a = 2 \ , b = - 10 \ , \ c = - 3 \\\\x = \frac{-b^2\ \pm \ \sqrt{b^2 - 4ac}}{2a}\\\\x = \frac{10 \ \pm \sqrt{(-10)^2 - ( 4 \times 2 \times -3)} }{2 \times 2}\\\\x = \frac{10 \ \pm \sqrt{(100 - ( -24 )} }{4}\\\\x = \frac{10 \ \pm \sqrt{(100 + 24 } }{4}\\\\x = \frac{ 10 \ \pm \sqrt{124}}{4}\\\\x = \frac{ 10 \ \pm \sqrt{4 \times 31}}{4}\\\\x = \frac{ 10 \ \pm \sqrt{2^2 \times 31}}{4}\\\\x = \frac{ 10 \ \pm2 \sqrt{31}}{4}\\\\x = \frac{ 5 \ \pm\sqrt{31}}{2}\\\\$

$x = \frac{ 5 \ + \ \sqrt{31}}{2} \ , \ x = \frac{ 5 \ - \ \sqrt{31}}{2}$

Use the order of operations to find the value of the following expression.

Romashka-Z-Leto [24]

10² - 2 (8) + 11 . Use PEMDAS, which is the order of operation to follow:

P = parenthesis  → 10² - 2x8 +11
E = exponent     → 100 - 2x8 +11
M = Multiplication → 100 -16 +11
D = Division         → NO DIVISION
A = Addition        → 111 -16
S = Subtraction  → 95 (answer 3)

Apply the same logic for the 2nd exercice and you will find 26 (I don't see the 26 in your answer but I am sure it's 26)

I have no idea how to solve this

Pavlova-9 [17]

Answer:

x = 25

Step-by-step explanation:

Hi there !

the opposite angles are equal

4x - 25 = 25 + 2x

4x - 2x = 25 + 25

2x = 50

x = 50 : 2

x = 25

Good luck !

Help Solve the following equations, and show/explain your work: 2x+4=18 and 25+3x=15.

nignag [31]

Answer:

2x+4=18

2x=18-4

2x=14

x=14/2

x=7

25+3x=15

3x=15-25

3x= -10

x= -10/3

x= -3.333
