To simplify the given algebraic expression $x(3x - 8) + 3(x^2-5) + 11$, we need to follow the order of operations and combine like terms.
First, apply the distributive property to the terms in parentheses:
Now, substitute these expanded forms back into the original expression:
$ (3x^2 - 8x) + (3x^2 - 15) + 11 $Remove the parentheses:
$ 3x^2 - 8x + 3x^2 - 15 + 11 $Next, group the like terms together. Like terms are terms that have the same variable raised to the same power.
Perform the combinations:
Putting it all together, the simplified expression is:
$ 6x^2 - 8x - 4 $This matches one of the options provided.
Simplify the following.
$4\left((\frac{3}{4})x^2 - 26x + 17\right) - 3(x^2 + 4x - 14)$
Simplify: $3\left((\frac{7}{3})x^2 - 25x + 12\right) - 7(x^2 + 9x - 13)$.
Simplify the following.
$3\left((\frac{6}{3})x^2 - 21x + 18\right) - 6(x^2 + 5x - 18)$
