What are the roots of the quadratic equation y equals 2x2 plus 3x-20?
2x2 + 3x - 20 = (x + 4)(2x - 5).
What are the x-intercepts of y equals 2x-3x-20?
y = 0 gives 0 = - x - 20 so that x = -20 So the intercept is (-20, 0)
Is y equals 3x plus 1 and -2x2 a function?
No.
What is 2x2 equals 3x?
2X2 = 3Xset to 02X2 - 3X = 0factorX(2X - 3) = 0zero factor rule2X = 3 = 02X = 3X = 3/2======X = 0X = 3/2
What is the solution set 2x2-3x-1 equals 0?
(-2,-1)
What are the x-intercepts of y 2x2 - 3x - 20?
They are at: x = -2.5 and x = 4
What are the x-intercepts of y equals 2x2 - 3x - 20?
y = 2x2 - 3x - 20 ∴ y = 2x2 - 8x + 5x - 20 ∴ y = 2x(x - 4) + 5(x - 4) ∴ y = (2x + 5)(x - 4) The x intercepts occur when y = 0, which happens when either of the two factors on the left side of the equation equal zero. This means that they are at the points (-5/2, 0) and (4, 0).
What are the roots of the quadratic equation y equals 2x2 plus 3x-20?
2x2 + 3x - 20 = (x + 4)(2x - 5).
2x2 - 3x plus 7?
2x2 equals 5
What are the x-intercepts of y equals 2x-3x-20?
y = 0 gives 0 = - x - 20 so that x = -20 So the intercept is (-20, 0)
Is y equals 3x plus 1 and -2x2 a function?
No.
How do you complete the square 2x2 - 3x plus 1 equals 0?
If: 2x2-3x+1 = 0 Then: x = 1 or x = 1/2
What is 2x2 equals 3x?
2X2 = 3Xset to 02X2 - 3X = 0factorX(2X - 3) = 0zero factor rule2X = 3 = 02X = 3X = 3/2======X = 0X = 3/2
What is the solution set 2x2-3x-1 equals 0?
(-2,-1)
What are the x-intercepts and Y-intercepts for the graph 3x plus 15 equals 5y?
X intercept: -5 Y intercept: +3
What are the intercepts of the line 3x 15y 60?
x=20 y=-3
