Answer:

Step-by-step explanation:

x^2 - 7x + 10 = 0

⇒a = 1                                            b = -7                                            c = 10

x^2 - 7x + 10 = 0

x^2 - 2x - 5x + 10 = 0

x(x - 2) - 5(x - 2) = 0

(x - 2)(x - 5) = 0

x - 2 = 0                                         OR                                      x - 5 = 0

     x = 2                                         OR                                           x = 5

Let,

α = 2                                            AND                                          β = 5

Now,

α + β = -b/a

2 + 5 = -(-7)/1

     7 = 7

α.β = c/a

2(5) = 10/1

  10 = 10
