Question

x(x+1)+3=2(2x+1)+4
how can we solve this​

Answer 1

Answer:

x(x+1)+3=2(2x+1)+4

x²+x+3 = 4x+2+4

x²+x-4x+3-6 = 0

x²-3x-3 = 0

x = 3/2+-√9+12/2

x = 3/2+-√21/2

Answer 2

Step-by-step explanation:

X(X+1)+3 = 2(2x+1)+4

or, x²+x+3 = 4x+2+4

or, x²+x = 4x+2+4-3

or, x²+x = 4x+3

or,x²+ x- 4x = 3

or, x²-3x = 3

or, x(x-3)= 3

or, x-3 = 3/X

or, x = 3x+3
