It's known as keep change and flip. Keep the first fraction, change the division sign into a multiplication sign, and flip the decimal to its reciprocal (switch the numerator and denominator). This is used when dividing fractions. We can even check to see if they have to same output.
2/5 × 5/2 = 1
8/9 × 5/2 = 40/18
2/5 ÷ 2/5 = 1
8/9 ÷ 2/5 = 40/18
Tell me if this helps, I can explain more if needed.

We want to find the zeros of this polynomial:
slava [35]

Answer:

x=-3        x=-1            x=2         x=-2

Step-by-step explanation:

p(x) = (x^2 + 4x + 3)(x^2 – 4)

Set this equal to zero to find the x intercepts

0 = (x^2 + 4x + 3)(x^2 – 4)

Using the zero product property

(x^2 + 4x + 3) =0      (x^2 – 4)  =0

Factor

(x+3)(x+1) =0            (x-2) (x+2)=0

Using the zero product property

x+3 =0  x+1 =0          x-2 =0  x+2 =0

x=-3        x=-1            x=2         x=-2
