Question

3t 2 - 5t 2 - 11t - 3t 2 +5t +11=

Answer 1

3t²-5t²-11t-3t²+5t+11=-5t²-6t+11
-5t²-6t+11=0
D=36-4*(-5)*11=36+220=256
D=√256=16
$x = \frac{6 + 16}{2 \times ( - 5)} = \frac{22}{ - 10} = 2 \frac{2}{10}$
$x = \frac{6 - 16}{ - 10} = \frac{ - 10}{ - 10} = 1$

Answer 2

To simplify the expression, you need to combine like terms. Like terms are terms that have the same variable(s) raised to the same exponent(s). Let's simplify the expression step by step:

1. Group the like terms together: (3t^2 - 5t^2 - 3t^2) + (-11t + 5t) + 11

2. Combine the like terms within each group: (-5t^2) + (-6t) + 11

3. Finally, combine the remaining like terms: -5t^2 - 6t + 11

So, the simplified expression is: -5t^2 - 6t + 11.
