Question

what is the x in x(x+3)=10

Answer 1

Answer:

x=2,x=-5

Step-by-step explanation:

x(x+3)=10

x^2+3x=10

x^2+3x-10=0

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

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

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

x=2,x=-5

Answer 2

Step-by-step explanation:

Q= X(X+3)=10

x²+3x-10

By splitting middle term

x²+3x-10

x²+5x-2x-10

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

(x-2)(x+5)

x=2 , x= -5
