## Answers ( No )

Answer:Given the equation:

rewrite the above equation as:

Like terms are those whose variables are same.Combine like terms :

….[1]

Now, to solve the above quadratic equation:

For quadratic equation: where a,b, and c are constant.then the solutions are:

…[2]

in equation [1], the values of a= 4, b=-10 and c= -24.

then, by putting these in the [2] we get,

On solving we get, the solutions are:

and

Check :By substituting the values of x= -1.5 and x=4 in equation we have;

for x=-1.5

9+10.5=19.5

19.5=19.

Similarly, for x=4

64-28=36

36=36

Therefore,

the only solution of the equationis,x= -1.5 and x=44×2 – 7x = 3x + 24

First we rewrite the quadratic equation:

4×2 – 7x – 3x – 24 = 0

4×2 – 10x – 24 = 0

The solutions to the quadratic equation in this case are:

x1 = 4

x2 = -1.5

Answer:x = -3/2x = 4
