Which expression is equivalent to x2+3x+ 3+ (2x+134+15) - (x+5))
tia_tia [17]

Answer:

x^{2} + ( 4x) + (147)

Step-by-step explanation:

Here, the given expression is

x^{2} +3x +3 + (2x+134+15) - (x+5)

Now, simplifying the brackets, we get

x^{2} +3x +3 + (2x+134+15) - (x+5) = x^{2} +3x +3 + 2x+134+15 - x -5

Now, operate on the like terms.

= x^{2} + ( 3x + 2x -x) + (134 + 15 + 3 -5)

=x^{2} + ( 4x) + (147)

Hence, the given expression is simplified to the quadratic equation x^{2} + ( 4x) + (147)
