We know that, In a Right Angled Triangle :
✿ (Hypotenuse)² = (First Leg)² + (Second Leg)²
From the Diagram :
✿ Hypotenuse = x
✿ First Leg 
✿ Second Leg 
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
The answer is - x 2-3
put x=1
(-1)2-3
-2 -3
=-5
