Solution

It appears that you've uploaded an image related to a quadratic equation problem. Based on what I can see, the equation provided is:

2x2+8x+10=02x^2 + 8x + 10 = 0

You're asked to use Vieta's formulas to find the sum and product of the roots of this equation.

Vieta's Formulas:

For a quadratic equation of the form ax2+bx+c=0ax^2 + bx + c = 0, Vieta's formulas tell us that:

  • The sum of the roots (x1+x2)(x_1 + x_2) is given by: Sum of roots=ba\text{Sum of roots} = -\frac{b}{a}
  • The product of the roots (x1x2)(x_1 \cdot x_2) is given by: Product of roots=ca\text{Product of roots} = \frac{c}{a}

Applying Vieta's Formulas to 2x2+8x+10=02x^2 + 8x + 10 = 0:

  • a=2a = 2, b=8b = 8, and c=10c = 10
  • The sum of the roots is: Sum of roots=82=4\text{Sum of roots} = -\frac{8}{2} = -4
  • The product of the roots is: Product of roots=102=5\text{Product of roots} = \frac{10}{2} = 5

Thus, the sum of the roots is -4, and the product of the roots is 5.
