Which expression is equivalent to

[tex]\left(-11 x^2 + 1.4 x - 3\right) + \left(4 x^2 - 2.7 x + 8\right)[/tex]?

A. [tex]-7 x^2 - 1.3 x + 5[/tex]
B. [tex]-7 x^2 + 1.3 x + 5[/tex]
C. [tex]7 x^2 - 1.3 x + 5[/tex]
D. [tex]7 x^2 + 1.3 x + 5[/tex]

Answer :

We start with the two expressions:
[tex]$$-11x^2 + 1.4x - 3 \quad \text{and} \quad 4x^2 - 2.7x + 8.$$[/tex]

1. Combine the [tex]$x^2$[/tex] terms:
[tex]$$-11x^2 + 4x^2 = -7x^2.$$[/tex]

2. Combine the [tex]$x$[/tex] terms:
[tex]$$1.4x - 2.7x = -1.3x.$$[/tex]

3. Combine the constant terms:
[tex]$$-3 + 8 = 5.$$[/tex]

Thus, the combined expression is:
[tex]$$-7x^2 - 1.3x + 5.$$[/tex]

This expression corresponds to option A.
