## Samacheer Kalvi Math Solution for Exercise 3.3 part 4

(iii) 0,4

Solution:

General form of quadratic equation with roots α and β is

x² - (α + β) x + αβ = 0

α = 0    β = 4

x² - (0 + 4) x + 0 (4) = 0

x² - 4 x = 0

(iv) 2,1/5

Solution:

General form of quadratic equation with roots α and β is

x² - (α + β) x + αβ = 0

α = √2    β = 1/5

x² - (√2 + (1/5)) x + √2 (1/5) = 0

x² - (5√2 + 1)/5 x + (√2/5) = 0

In the page samacheer kalvi math solution for exercise 3.3 part 4 we are going to see the solution of next problem

(v) 1/3,1

Solution:

General form of quadratic equation with roots α and β is

x² - (α + β) x + αβ = 0

α = 1/3    β = 1

x² - ((1/3) + 1) x + (1/3) (1) = 0

x² - [(1 + 3)/3] x + (1/3) = 0

x² - (4/3) x + (1/3) = 0

3x² - 4 x + 1 = 0

(vi) 1/2, -4

Solution:

General form of quadratic equation with roots α and β is

x² - (α + β) x + αβ = 0

α = 1/2    β = -4

x² - ((1/2) + (-4)) x + (1/2) (-4) = 0

x² - [(1 - 8)/2] x + (1/3) = 0

x² - (4/3) x + (1/3) = 0

3x² - 4 x + 1 = 0

(vii) 1/3,1/3

Solution:

General form of quadratic equation with roots α and β is

x² - (α + β) x + αβ = 0

α = 1/3    β = 1/3

x² - ((1/3) + (1/3)) x + (1/3) (1/3) = 0

x² - [(1 + 1)/3] x + (1/9) = 0

x² - (2/3) x + (1/9) = 0

9x² - 6 x + 1 = 0

(viii) √3 , 2

Solution:

General form of quadratic equation with roots α and β is

x² - (α + β) x + αβ = 0

α = √3   β = 2

x² - (√3 + 2) x + (√3) 2 = 0

x² - (2 + √3) x + 2√3 = 0
