Question

i) x2 – 3x – 10 = 0​

Answer 1

Answer:

Using middle term factorisation

x²-3x-10=0

x²+2x-5x-10=0

x(x+2) -5(x+2)

(x-5) (x+2)

x-5 x+2

x=5 x=-2

Hope you will understand.

Answer 2

Answer:

x= 5, -2

Step-by-step explanation:

x2 – 3x – 10 = 0

x2 - 5x + 2x - 10 = 0

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

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

x= 5, -2
