Question

quadratic equation (x+1)(x+2) = x2( x+1) solution​

Answer 1

Answer:

$(x + 1)(x + 2) = 2x(x + 1) \\ {x}^{2} + 2x + x + 2 = 2 {x}^{2} + 2x \\ {x}^{2} - x - 2 = 0$

hope it's helpful

Answer 2

Answer:

1. if x2 means x square then x= -1,2

2. if x2 means x multiply 2 then x= -1,2

Step-by-step explanation:

1.

(x+1)(x+2)=x2(x+1)

(x+1)(x+2-x2)=0

x+1=0 and x2-x-2=0

x=-1 and x2-2x+x-2=0

x=-1 and (x-2)(x+1)=0

x=-1 and x=2,-1

2.

(x+1)(x+2)=x2(x+1)

(x+1)(x+2-2x)=0

(x+1)(2-x)=0

x= -1,2

for both case x=-1,2
