Question

Solve the following quadratic equation by factorisation
x^2+11 x+30= 0

Answer 1

Answer:

x^2+11 x+30= 0

=>x^2+6x+5x+30= 0

=>x(x+6)+5(x+6)=0

=>(x+6)(x+5)=0

=>x=-5 or x=-6

Answer 2

Answer:

x = -6

x = -5

Step-by-step explanation:

Find integer pairs

a = 5

b = 6

(x +5) (x + 6)

x +5 = 0

x = 0 -5

  = -5

x + 6 = 0

x = 0 -6

  = -6

x = -6 , x = -5
