The value of q is 40
Step-by-step explanation:
In the quadratic equation ax² - bx + c = 0, where
- a = 1
- b is the sum of its two roots
- c is the product of its two roots
Assume that the roots of the quadratic equations are x and y
∵ The quadratic equation is x² - 14x + q = 0
∴ a = 1 , b = 14 and c = q
∵ b is the sum of its two roots
∵ Its roots are x and y
∴ x + y = 14 ⇒ (1)
∵ The difference between the roots is 6
∴ x - y = 6 ⇒ (2)
Now we have a system of equation to solve it
Add equations (1) and (2)
∴ 2x = 20
- Divide both sides by 2
∴ x = 10
Substitute the value of x in equation (1) or (2) to find y
∵ 10 + y = 14
- Subtract 10 from both sides
∴ y = 4
∵ c is the product of the two roots
∴ c = 10 × 4 = 40
∵ c = q
∴ q = 40
The value of q is 40

Step-by-step explanation:
When putting a set of points into y=mx+b you require the slope and y intercept. to find the y intercept and end with a simplified equation use
<u>y-y1=m(x-x1)</u>
m is the slope, x1 is the first number in a set of points and y1 is the second number in a set of points.
If you need the slope use the slope formula y2-y1/x2-x1. this only works with at least two sets of points.
y2 is the second number in the second set of points. x2 is the first number in the second set of points.
