{a }^{2}  +   {b}^{2} =  {c}^{2}

{1}^{2}  +  {x}^{2}  =  {2}^{2}
{x}^{2}  =  {2}^{2}  - {1}^{2}
{x}^{2}  = 3 \\  \\ x =  \sqrt{3}
\sqrt{3}  = 1.73

The correct simplification of 8x2(5x 2x2 − 3) is 16x^{4} +40x^{3} -24x^{2}

<h3>What do you mean by simplification?</h3>
  • Simplifying procedures is one way to achieve uniformity in work efforts, expenses, and time. It reduces diversity and variety that is pointless, harmful, or unnecessary.
  • Making anything simpler is the act or process of simplification. Everyone is in favor of streamlining court procedures.
  • Certain "solving" issues are connected to "simplification" issues. Parentheses and even nested grouping symbols can be found in some equations, just like in some expressions. Whether we're working with equations (so we're also solving) or expressions (and only simplifying), the simplification procedure is the same in both cases.

The correct simplification of 8x2(5x 2x2 − 3).

8x^{2} (5x+2x^{2+1} -3)=8*2x^{2+2} -8*3x^{2}

                                =40x^{3} +16x^{4} -24x^{2}

Rearranging the above expression in descending order of power, we get:16x^{4} +40x^{3} -24x^{2}

The correct simplification of 8x2(5x 2x2 − 3) is 16x^{4} +40x^{3} -24x^{2}

Evaluate the function f(x)=x^2+6x+2 at the given values of the independent variable and simplify.
____ [38]

Answer:

a) 18

b)x^2+10x+18

c)x^2 -6x+2

Step-by-step explanation:

This is a case of plugging in the value into f(x).

a) f(-8)= -8^2 + 6(-8) +2

f(-8)= 64 + (-48) +2

f(-8)=64 + (-46)

f(-8)=18

b)  f(x+2)= (x+2)^2+6(x+2)+2

So here I'll take a break to explain what's going on, because x+2 is a binomial meaning two terms and it is being squared I have to multiply the whole thing by itself. Meaning: (x+2) x (x+2), this is also known as foiling!! and for the next part its distributing 6 into x and 2.

    f(x+2)= x^2+4x+4+6x+12+2

I'll reorder it

 f(x+2)= x^2+4x+6x+12+2+4

    f(x+2)= x^2+10x+18

c) f(-x)= -x^2+6(-x) +2

f(-x)= x^2 -6x+2
