Answer:
Step-by-step explanation:
At first you need to turn roots into factors and then multiply the
then you have
f(x) = a(x + 2)(x -5)^2
f(x) = a(x + 2)(x^2 - 10x + 25)
f(x) = a(x^3 - 8x^2 + 5x + 50)
You can use either synthetical or the factor
theorem
f(-2) = a(-8 - 8(4) + 5(-2) + 50) = a(0) = 0.. check, f
=-2
€(5) = a(125 - 8(25) + 5(5) + 50) = a(0) = 0 check, f
= 5 works
Then divide it to the the second multi
And you should get x^2 - 3x - 10 = (x - 5)(x + 2),
where the other two zeros are X =5 , and x=-2
Answer:
Step-by-step explanation:
<u>As per diagram we have:</u>
<u>As per 30° right triangle property:</u>
- CD = √3×CB/2 = 3√3 ≈ 5.2 cm
- and
- AC = 2CD = 2×5.2 = 10.4 cm
<u>Area of triangle:</u>
- A = 1/2bh
- A = 1/2CB*AC
- A = 1/2*5.2*10.4 ≈ 27 cm²
