The sum and the product of the zeros of the polynomial 2x²-x-6​

Sum = .5 Product = -3

Step-by-step explanation:

for number one its -x+10y=14x+10y=21 the next one is Simplifying

-7x + -5y = 11

Solving

-7x + -5y = 11

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '5y' to each side of the equation.

-7x + -5y + 5y = 11 + 5y

Combine like terms: -5y + 5y = 0

-7x + 0 = 11 + 5y

-7x = 11 + 5y

Divide each side by '-7'.

x = -1.571428571 + -0.7142857143y

Simplifying

x = -1.571428571 + -0.7142857143y
