Answer:

\tt   \huge \boxed{ \boxed{\color{silver}  { - 3x}^{2}  + 6x - 4}}

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>
  • algebra
  • algebraic addition subtraction
  • PEMDAS
<h3>tips and formulas:</h3>
  • quadratic expression standard form:ax²+bx+c
  • order of PEMDAS
  1. parentheses
  2. exponent
  3. multiplication or
  4. division
  5. addition
  6. subtraction
  • left to right
<h3>given:</h3>
  • 4x+7-8x²+2x+5x²-11
<h3>to do</h3>
  • simplification
<h3>let's do:</h3>

step - 1  : define

\sf 4x + 7 -  {8x}^{2}  + 2x +  {5x}^{2}  - 11

step - 2 : simplify

  1. \tt \: rewrite  : \\ \sf {8x}^{2}  +  {5x}^{2}   + 4x + 2x + 7 - 11
  2. \tt \:combine \: like \: terms: \\ \sf { - 3x}^{2}      + 6x + 7 - 11
  3. \tt \: substrak :  \\ \sf  { - 3x}^{2}  + 6x - 4

therefore

we can see the expression is in standard form since a,b and c is -3,6 and -4

also let's justify it

substitute the value of a,b and c respectively

(-3)x²+(6)x+(-4)

-3x²+6x-4 (proven)

  • (4⁰)-⁹

= 4⁰×-⁹

= 4⁰

  • (-4⁹)²

= -4⁹ײ

= -4¹⁸

=( -4)¹⁸

  • (4-³)-³

= 4-³ × -³

= 4⁹

  • (4⁶)-³

= 4⁶ × -³

= 4-¹⁸
