Q. −2−x=11y2−4y+10−11x+3y=62If (x1,y1) and x2,y2) are two distinct solutions to the system of equations shown, what is the product of the x values of the two solutions (x1∗x2)?
Solve First Equation: First, let's solve the system of equations using substitution or elimination. I'll start with the first equation:−2−x=11y2−4y+10Multiply both sides by 11 to get rid of the fraction:−22−11x=y2−4y+10
Rearrange Second Equation: Now let's rearrange the second equation to express y in terms of x: −11x+3y=62 3y=11x+62 y=311x+62
Substitute y into First: Substitute the expression for y from the second equation into the first equation:\(-22 - 11x = \left(\frac{11x + 62}{3}\right)^2 - 4\left(\frac{11x + 62}{3}\right) + 10
Expand and Simplify: Now, let's expand and simplify the equation:−22−11x=9121x2+1342x+3844−344x+248+10
Combine Like Terms: To combine the terms, we need a common denominator, which is 9: −198−99x=121x2+1342x+3844−132x−744+90
Factor or Use Quadratic Formula: Combine like terms:121x2+1342x−132x+3844−744+90=99x+198121x2+1210x+3190=99x+198
Calculate Discriminant: Bring all terms to one side to set the equation to zero:121x2+1210x−99x+3190−198=0121x2+1111x+2992=0
Plug in Values: Now we need to factor the quadratic equation, but it seems a bit complicated. Let's use the quadratic formula instead:x=2a−b±b2−4acHere, a=121, b=1111, and c=2992.
Calculate Exact Value: Calculate the discriminant b2−4ac:Discriminant=11112−4(121)(2992)
Calculate Exact Value: Calculate the discriminant b2−4ac: Discriminant = 11112−4(121)(2992)Plug in the values and calculate the discriminant: Discriminant = 1234321−4(121)(2992)
Calculate Exact Value: Calculate the discriminant b2−4ac: Discriminant = 11112−4(121)(2992)Plug in the values and calculate the discriminant: Discriminant = 1234321−4(121)(2992)Calculate the exact value of the discriminant: Discriminant = 1234321−1448448 Discriminant = (-214127\)
