Answer:
x² - x - 6
Step-by-step explanation:
Step 1: Write expression
(5x² + 2x - 5) - (3x² + 3x + 1)
Step 2: Distribute negative
5x² + 2x - 5 - 3x² - 3x - 1
Step 3: Combine like terms (x²)
2x² + 2x - 5 - 3x - 1
Step 4: Combine like terms (x)
x² - x - 5 - 1
Step 5: Combine like terms (constants)
x² - x - 6
Answer:
y - intercept. = 2.
Step-by-step explanation:
Given : The equation of a line is 5x − 3y = 6.
To find : Which is the y-intercept of the line.
Solution : We have given 5x − 3y = 6.
Equation of line y = mx +b
Where , m = slope , y intercept = b
Now we convert the 5x − 3y = 6 in line form y = mx +b
5x − 3y = 6
On subtracting both sides by 5x
-3x = - 5x + 6
On dividing both sides by - 3.
x =
.
We cans see m =
, y - intercept. = 2.
Therefore, y - intercept. = 2.
Answer:
11/5
Step-by-step explanation:
FirLet a and b be the roots of 11x^2-4x-2=0
Now
Dividing the quadratic equation by 11 we have

Now the sum of the roots is the minus of the coefficient of x and the product of the roots is the constant. Therefore

and we have
