Do what?  If you mean to find when it equals zero...

By inspection you can see that if x=0 or 2 the expression is equal to zero...

You multiply each term in the parentheses by the term outside the parentheses...like:

3x*3x+3x*6 which is equal to:

9x^2+18x   If you meant to expand it....

9x(x+2)      If you meant to factor it completely

Answer:

Step-by-step explanation:

Step 1: Variables

phenotypic variation (Vp)

genotype variation (Vg)

environment variation (Ve)

broad sense heritability (H)

Step 2: Formulas:

H = Vg / Vp

Vp = Vg + Ve

Vg = Vp - Ve

Step 3: Given data

Vp = 20

Ve = 5

Step 4: Computation

Vg = 20 - 5 = 15

H = 15 / 20

H = 0.75

Hope this helps!

Answer:

0.6

Step-by-step explanation:

Given the trapezoid formula:

1/2(b1+b2/2)xH

We are given the numbers for the trapezoid:

0.3,0.9,1

To solve this here is what we are going to do.

1/2(0.9+0.3)x1

So add 0.9+0.3=1.2

Then Divide 1.2/2=0.6

So multiply 0.6 x 1=0.6

0.6 is your answer
