Answer:
Step-by-step explanation:
<u>Standard for of quadratic equation:</u>
<u>We have </u>
<u>Sum of the roots </u>
- x₁ + x₂ = - b/a = -(-5)/2 = 2.5
<u>Product of the roots </u>
<u>We have:</u>
<u>The square of the above is:</u>
- (x₁ - x₂)² = (x₁ + x₂)² - 4x₁x₂
<u>Substitute known values and solve for c:</u>
- 0.25² = (2.5)² - 4(c/2)
- 2c = 6.25 - 0.0625
- 2c = 6.1875
- c = 3.09375
20,000 + 5,000 + 300 + 2 = 25302
25,302 x 1 = 25,302
24,000 + 1302 = 25302
25,000 + 302 = 25302
Answer:
to be honest i don't think the distributive property is needed for this problem correct me if i'm wrong though
the answer is 200 though
