Solve the Quadratic Equation

Mathematics
1 answer:
UNO [17]3 years ago
7 0

Answer:

-4.54 and 1.54

Step-by-step explanation:

This is a quadratic equation

Let Δ be our discriminant :

  • a= 1
  • b= 3
  • c= -7
  • Δ = 3²-4*1*(-7)= 37≥0

so we have two solutions : x and y

x =( -3-\sqrt{37})/2 = -4.54

y= ( -3+\sqrt{37})/2= 1.541

then the solutions are -4.54 and 1.54

8k - 6 = 10k + 6<br> No idea how to figure this out
kumpel [21]

8k - 6 = 10k + 6

K= -6

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    8*k-6-(10*k+6)=0

Step by step solution :

STEP

1

:

Pulling out like terms

1.1     Pull out like factors :

  -2k - 12  =   -2 • (k + 6)

Equation at the end of step

1

:

STEP

2

:

Equations which are never true:

2.1      Solve :    -2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

2.2      Solve  :    k+6 = 0

Subtract  6  from both sides of the equation :

   Which gives k = -6

Andrea needs 4 kilograms of oranges. The scale below shows the weight of the oranges she has in her kitchen. Part A. About how m
juin [17]
We know that

<span>each space on the balance represents
1 kg/ 10 spaces----------> 0.10 kg
in the picture there are 14 spaces
so
14*0.1-------> 1.4 Kg
</span>
Part A) About how many kilograms of oranges does Andrea have? Round your answer to the nearest kilogram

Andrea has 1.4 kg of oranges------> to the nearest kilogram-----> 1 Kg

the answer is
1 kg

Part B) About how many more kilograms of oranges does Andrea need?
Andrea needs=(4 Kg-1.4 Kg)------> 2.6 Kg

the answer part B) is

Use the Remainder Theorem to find the remainder for (x^4-6x^2+8)divided(x-rad2) and state whether or not the binomial is a facto
Rom4ik [11]

Answer:

Step-by-step explanation:

put x-√2=0

x=√2

put x=√2 in x^4-6x^2+8

we get (√2)^4-6(√2)²+8

=4-12+8

=0

Remainder=0

and x-√2 is a factor of the given polynomial.
