Question

x(2x+5)=3
please solve the equation​

Answer 1

Answer:

DID YOU MEAN:

x(2x+5)=3

Simplify.

2x²+5x-3=0.

Split the middle term.

2x²+6x-1x-3=0

2x(x+3)-1(x+3)=0

(2x-1)(x+3)=0.

Thus, 2x-1=0 ; x+3=0, that is,

x=0.5 ; -3.

The graph of this equation is shown in the file attached.

You can see that the line intersects x-axis of the graph at (0.5,0) and (-3,0). Thus, the abscissa of the points of x axis, i.e., 0.5 and -3, are the roots.

OR DID YOU MEAN:

2x+5=3

2x=3-5

x= -1.

HOPE THIS HELPS :D
