Question

What is (a^2−11)+(3a^2−4a+6) ?(1 point) Responses −5 negative 5 3a^2−4a−5 3 a squared minus 4 a minus 5 −4a^2+4a+5 negative 4 a squared plus 4 a plus 5 4a^2−4a−5

Answer 1

To simplify the expression (a^2−11)+(3a^2−4a+6), we can combine the like terms.

The like terms in the expression are the ones with the same power of 'a'.

a^2 + 3a^2 = 4a^2

-11 + 6 = -5

-4a = -4a

Putting these together, we have:

(4a^2) + (-5) + (-4a) = 4a^2 - 4a - 5

So, the simplified form of (a^2−11)+(3a^2−4a+6) is 4a^2 - 4a - 5.
