I don't know specifically what the sum and product of an equation is but

factor using quadratic formula

if you have an equation in ax^2+bx+c=0 then you can solve for x using

x= \frac{-b+ \sqrt{b^2-4ac} }{2a}  or  x= \frac{-b- \sqrt{b^2-4ac} }{2a}

so input
a=1
b=7
c=2

x= \frac{-7+ \sqrt{7^2-4(1)(2)} }{2(1)}
x= \frac{-7+ \sqrt{49-8} }{2}
x= \frac{-7+ \sqrt{41} }{2}=aprox -0.2984378812836

x= \frac{-7- \sqrt{7^2-4(1)(2)} }{2(1)}
x= \frac{-7- \sqrt{49-8} }{2}
x= \frac{-7 \sqrt{41} }{2}=aprox  -6.7015621187165

Answer:

Value of x using quadratic formula (x = -4) and (x = -5)

Step-by-step explanation:

Given:

Equation

x² + 9x + 20 = 0

Find:

Value of x using quadratic formula

Computation:

Quadratic formula = [-b±√b²-4ac] / 2a

Given equation;

x² + 9x + 20 = 0

a = 1 , b = 9 , c = 20

By putting value

[-9±√9²-4(1)(20)] / 2(1)

[-9±√81-80] / 2

[-9±√1] / 2

(-9 + 1) / 2 , (-9 - 1) / 2

-8 / 2 , 10 / 2

-4 , - 5

Value of x using quadratic formula (x = -4) and (x = -5)

alukav5142 [94]

This is a vertical line that goes through all points with an x-coordinate of -9.

To graph it, I can give you a couple of points this line goes through so you can draw it more easily.

Points that are on line: (-9,0) and (-9,1)
