What are two numbers whose sum is negative twenty six and product is forty?
Let the numbers be x and ythen we have x+y=-26 and xy=40So x=40/yNow x+40/x=-26so x2 + 40+26x=0or x2 +26x +40=0You could solve this with the quadratic equation but let's complete the squarex2 +26x +40=0 is the same as(x+13)2 +40-169=0(x+13)2 =129x+13= + or = Square root of 129x=-13+square root of 129 or x=-13-square root of 129So the answers are =-13+(square root 129)-13 - square root of 129Their sum is clearly -13+-13=-26and their product is 40If you need natural numbers or rational numbers, then there is no solution, however if you want any two NUMBERS, then that is the answer.
30x2 - 26x plus 4 equals 0?
Factors are (3x - 2)(10x - 2) so x = 2/3 or 1/5 Check: 30 x 4/9 - 26 x 2/3 = 120/9 - 52/3 = -12/3 = -4 OK 30 x 1/25 - 26/5 =30/25 - 26/5 = 6/5 - 26/5 = 20/5 = -4 OK 60

Where are the points of contact made on the x and y axes when y equals 8x2 -26x plus 15?
The x-axis is y = 0 → y = 8x² - 26x + 15 → 0 = 8x² - 26x + 15 = (4x - 3)(2x - 5) So 4x - 3 = 0 → 4x = 3 → x = ¾ = 0.75 or 2x -5 = 0 → 2x = 5 → x = 2½ = 2.5 The y-axis is x = 0 → y = 8x² - 26x + 15 = 8 × 0² - 26 × 0 + 15 = 15 → The points of contact with the x- and y- axes of y = 8x² - 26x + 15 are: (0.75, 0), (2.5, 0), (0, 15)
