Answers: Using the process of completing the square:
1. Isolate the constant by <u>adding 7 to</u> both sides of the equation:
x^2-6x-7+7=0+7
x^2-6x=7
2. Add <u>9</u> to both sides of x2 – 6x = 7 to form a perfect square trinomial while keeping the equation balanced:
x^2-6x+9=7+9
x^2-6x+9=16
3. Write the trinomial x2 – 6x + 9 as squared:
<u>(x-3)^2</u> = 16
4. Use the square root property of equality to get x – 3 = ±<u>4</u> .
sqrt[ (x-3)^2 ] = ± sqrt(16)
x-3 = ±4
5. Isolate the variable to get solutions of –1 and 7.
x-3 = ±4
x-3+3 = ±4+3
x = ±4+3
x1=-4+3→x1=-1
x2=+4+3→x2=7
A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables. imports of coffee into a country during this years 1997 is 1.344
<h3>What is a polynomial?</h3>
a polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables.
P(x)=0.7166x²+6.267x+1.344
when x = 0, it represents 1997
Substitute the value of x as zero in polynomial.
P(0)=0.7166(0)²+6.267(0)+1.344
P(0)=0+0+1.344
P(0)=1.344
The amount of coffee imported in the year 1997 was approximately 1.344 pounds.
Hence amount of coffee imported in the year 1997 was approximately 1.344 pounds.
