I need help simplifying both of these. thank you!
4vir4ik [10]
<h3>Answer:</h3>
  1. -100x +100; 3
  2. 5x +81; 162
<h3>Step-by-step explanation:</h3>

The distributive property is your friend. It tells you ...

  a(b + c) = ab + ac

It can also be used to simplify the product of binomials (or other polynomials).

  (a +b)^2 = (a +b)(a +b) = a(a +b) + b(a +b) = a^2 +ab +ab +b^2

  (a +b)^2 = a^2 +2ab + b^2 . . . . . . . worth remembering

1. (x -10)^2 -x(x +80) = (x^2 -20x +100) +(-x^2 -80x)

  = -100x +100 . . . . . . simplified form

For the purposes of calculation, it can be easier to factor out 100:

  = 100 (1 -x)

Then for x = 0.97

  = 100(1 -0.97) = 100(0.03) = 3

___

2. (2x +9)^2 -x(4x +31) = (4x^2 +36x +81) -4x^2 -31x = 5x +81

For x = 16.2, this is ...

  5(16.2) +81 = 81 +81 = 162

_____

The purpose of the attachment is to show the evaluation is correct.

Choose the quadratic equation that has a leading coefficient of 1 and solutions 3 and -2.
ss7ja [257]

Answer:

Option D x^{2} -x-6=0

Step-by-step explanation:

Verify each quadratic equation

case A) we have

x^{2} +x+6=0

This quadratic equation has a leading coefficient of 1

Substitute the value of x=3 and x=-2 in the equation

For x=3

(3)^{2} +(3)+6=0

18=0 ----> is not true

therefore

x=3 is not a solution of the quadratic equation

case B) we have

x^{2} -x-5=0

This quadratic equation has a leading coefficient of 1

Substitute the value of x=3 and x=-2 in the equation

For x=3

(3)^{2} -(3)-5=0

1=0 ----> is not true

therefore

x=3 is not a solution of the quadratic equation

case C) we have

x^{2} +x+5=0

This quadratic equation has a leading coefficient of 1

Substitute the value of x=3 and x=-2 in the equation

For x=3

(3)^{2} +(3)+5=0

17=0 ----> is not true

therefore

x=3 is not a solution of the quadratic equation

case D) we have

x^{2} -x-6=0

This quadratic equation has a leading coefficient of 1

Substitute the value of x=3 and x=-2 in the equation

For x=3

(3)^{2} -(3)-6=0

0=0 ----> is true

therefore

x=3 is a solution of the quadratic equation

For x=-2

(-2)^{2} -(-2)-6=0

4+2-6=0

0=0 ----> is true

therefore

x=-2 is a solution of the quadratic equation
