Question

solve
by factarise method
salue x²-3x - 10=0
​

Answer 1

Step-by-step explanation:

x²-3x - 10=0

x^2-5x+2x-10 = x(x-5)+2(x-5)

x²-3x - 10= (x+2)(x-5)

So value of x= 5

Answer 2

Answer:

x= -2 x= 5

Step-by-step explanation:

x²-3x - 10=0

x²-5x +2x- 10=0

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

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

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

x = - 2 x = 5
