What is the first step in solving the following equation
Naily [24]

Answer:

The first step in solving the equation is "set each binomial factor equal to zero" ⇒ 3

Step-by-step explanation:

To solve a quadratic equation y = ax² + bx + c

  • Put y = 0
  • Factorize it into two binomial factors (x ± m)(x ± n)
  • Equate each binomial factor by 0 to find the values of x
  • The values of x are the solution of the equation

∵ The equation is (x + 2)(x - 3) = 0

∵ The equation equated by 0

∵ It is factored into 2 binomial factors (x + 2) and (x - 3)

- The next step is equated each factor by 0 to find the values of x

∴ The 1st step in solving (x + 2)(x - 3) = 0 is set x + 2 = 0 and

   x - 3 = 0

The first step in solving the equation is "set each binomial factor equal to zero"

when 9 is subtracted from the square of a number, the result is 8 times the number.Find the negative soulution.PLZ HELP FAST
frozen [14]

Answer:

The negative solution  k = -1 is the desired solution.

Step-by-step explanation:

Let the given number = k

So, according to the question:

k^{2}  - 9 = 8k

or, k^{2}  - 8k - 9 = 0

Now, solving this quadratic equation, we get

\implies k^{2}  - 9k + k - 9 = 0

or, k ( k-9) + 1 (k-9) = 0

⇒( k-9)(k+1)  = 0

or, ( k-9)  = 0 , or (k+1)  = 0

⇒  k  = 9  or  k  = -1

Since we only want the negative solution , the k = -1 is the desired solution.
