Question

solve x2-15×+50=0 by factorisation​

Answer 1

Answer:

5 or 10

Step-by-step explanation:

x2-15x+50=0

x2-5x-10x+50=0

x(x-5)-10(x-5)=0

(x-5)(x-10)=0.

Therefore,x-5=0

x=5

Therefore,x-10=0

x=10

The value of x can be 5 or 10 according to the conditions given.

The equation is solved using middle term factorisation.
