What is the sum of the solutions of x2 + 9x + 20 = 0?
ZanzabumX [31]

Answer:

Sum of the solutions of x^2+9x+20=0 is -9.

Product of the solutions of 6x^2+7x=3 is -0.50

Step-by-step explanation:

1. x^2+9x+20=0

Given:

The expression whose sum of the solution is required is given as:

x^{2} +9x+20=0

For a quadratic equation of the form ax^2+bx+c=0 the sum of the solutions is given as:

Sum = \frac{-b}{a}

Here, a=1,b=9,c=20

Therefore, the sum of the solutions = -\frac{9}{1}=-9

2. 6x^2+7x=3

Rewriting the above equation in a standard quadratic equation, we get:

6x^2+7x-3=0

For a quadratic equation of the form ax^2+bx+c=0 the product of the solutions is given as:

Product = \frac{c}{a}

Here, a=6,b=7,c=-3

Therefore, the product of the solutions = \frac{-3}{6}=-0.50
