STALIN [3.7K]
Use distributive property: multiply the number outside the bracket by each number inside it

1. 14x+21=35 14x=14 x=1
2. -32x-24=40 -32x=64 x= -2
3. 16-10x=-44 -10x=-60 x=6

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"
