A number multiplied by itself added to itself equals 30 what are the two possible numbers?
('x' times 'x') plus 'x' = 30x2 + x - 30 = 0(x + 6) (x - 5) = 0x = -6and/orx = 5
What is the answer to A plus B plus C equals A times B equals C?
A=0 b=0 c=0
Put the equation in the form ax2 plus bx plus c equals 0 x2-3 equals 3x2 plus 8x?
2x^2 + 8x + 3 = 0
Can you put the equation x2 - 5 -4x2 plus 3x equals 0 in the form ax2 plus bx plus c equals 0?
x2-5-4x2+3x = 0 -3x2+3x-5 = 0 or as 3x2-3x+5 = 0
0 equals 2.5y plus 20?
y equals negative 8.
What is the solution for 30x2-28x plus 6 equals 0?
x=1/3,3/5
What number must you add to complete the square x2 plus 26x equals 68?
x2+26x = 68 x2+26x-68 = 0 (x+13)2-68 = 0 (x+13)2-169-68 = 0 x+13 = +/- the square root of 237 x = -13 +/- the square root of 237
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)
What number you must add to complete the square xsquared plus 26x equals 68?
x2+26x = 68 Completing the square: (x+13)2-169-68 = 0 (x+13)2-237 = 0 x+13 = -/+ sq rt 237 x = -13-/+ sq rt 237
Find the solution to the equation 20x2-26x plus 8 equals 0?
(10x - 8)(2x - 1) = 0 x = 4/5 or 1/2. It's easier to check in decimal: 0.8 or 0.5
What is the solution of 20x 2-26x plus 8 0?
The answer to this equation would be 5. This is a math problem.
Where are the points of intersection with the x and y axes when y equals 8x2 -26x plus 15 is plotted on the Catesian plane?
Equation: y = 8x^2 -26x+15 Equation when factorized: y = (4x-3)(2x-5) When x = 0 then y = (0, 15) which is the point of intersection on the y axis When y = 0 then x = (3/4, 0) and (5/2, 0) which are the points of intersection on the x axis
A number multiplied by itself added to itself equals 30 what are the two possible numbers?
('x' times 'x') plus 'x' = 30x2 + x - 30 = 0(x + 6) (x - 5) = 0x = -6and/orx = 5
CAN 0 plus equals B plus equals B?
Yes because if 1+0=1 than 0 plus b equals b
What is the answer to A plus B plus C equals A times B equals C?
A=0 b=0 c=0
What are the solutions of the equation x2-x equals 30?
-28
0 plus 0 equals 100?
No.
