Write the quadratic equation whose roots are 6 and 3, and whose leading coefficient is 4
nekit [7.7K]

If α and β are the Roots of a Quadratic Equation ax² + bx + c then :

✿  Sum of the Roots : α + β \mathsf{= \frac{-b}{a}}

✿  Product of the Roots : αβ \mathsf{= \frac{c}{a}}

Let the Quadratic Equation we need to find be : ax² + bx + c = 0

Given : The Roots of a Quadratic Equation are 6 and 3

⇒ α = 6 and β = 3

Given : The Leading Coefficient of the Quadratic Equation is 4

Leading Coefficient is the Coefficient written beside the Variable with Highest Degree. In a Quadratic Equation, Highest Degree is 2

Leading Coefficient of our Quadratic Equation is (a)

⇒ a = 4

⇒ Sum of the Roots \mathsf{: (6 + 3) = \frac{-b}{4}}

⇒ -b = 9(4)

⇒ b = -36

⇒ Product of the Roots \mathsf{: (6 \times 3) = \frac{c}{4}}

⇒ c = 18 × 4

⇒ c = 72

⇒ The Quadratic Equation is 4x² - 36x + 72 = 0

The answer to this question is true. The equation (x-h)^2+(y-k)^2 = r^2 represents a circle with a center at (h,k). Taking (h,k) = (-2,2) and r = 3 results in (x+2)^2 + (y-2)^2 = 9. A negative subtracted by a negative is a positive.
