What are the solutions to 9x2 plus 7x equals 2?
9x2 + 7x = 2 9x2 + 7x - 2 = 0 9x2 + 9x - 2x - 2 = 0 9x(x + 1) - 2(x + 1) = 0 (9x - 2)(x + 1) = 0 x ∈ {-1, 2/9}
9x2-18x plus 9 equals 0 what is the discriminant?
The discriminant is 0.
What are the intercepts of 9x2 plus 4y equals 36?
9x2 + 4y = 36∴ 4y = 36 - 9x2∴ y = 9 - 9x2/4also:∴ 9x2 = 36 - 4y∴ x2 = 4 - 4y/9∴ x = (4 - 4y/9)1/2This equation represents a parabolic curve, so we know it will intercept the y-axis at one point, and the x-axis at either zero or two points. Let's start with the x-axis:y = 9 - 9x2/4Let y = 0:∴ 0 = 9 - 9x2/4∴ 0 = 36 - 9x2∴ 9x2 = 36∴ x2 = 4∴ x = +/- 2So the curve intercepts the x axis at the points -2, 0 and 2, 0As for the y axis:x = (4 - 4y/9)1/2Let x = 0:∴ 0 = (4 - 4y/9)1/2∴ 0 = 4 - 4y/9∴ 0 = 45 - 4y∴ 4y = 45∴ y = 45/4 = 11 1/4So the curve intercepts the y axis at the point 0, 11.25
What are the solutions to this equation 9x2 plus 6x-7 equals 0?

What are the intercepts of 9x2 plus 4y equals 36?
9x2 + 4y = 36∴ 4y = 36 - 9x2∴ y = 9 - 9x2/4also:∴ 9x2 = 36 - 4y∴ x2 = 4 - 4y/9∴ x = (4 - 4y/9)1/2This equation represents a parabolic curve, so we know it will intercept the y-axis at one point, and the x-axis at either zero or two points. Let's start with the x-axis:y = 9 - 9x2/4Let y = 0:∴ 0 = 9 - 9x2/4∴ 0 = 36 - 9x2∴ 9x2 = 36∴ x2 = 4∴ x = +/- 2So the curve intercepts the x axis at the points -2, 0 and 2, 0As for the y axis:x = (4 - 4y/9)1/2Let x = 0:∴ 0 = (4 - 4y/9)1/2∴ 0 = 4 - 4y/9∴ 0 = 45 - 4y∴ 4y = 45∴ y = 45/4 = 11 1/4So the curve intercepts the y axis at the point 0, 11.25

How would you factor x3 9x2 27x 27?
x3 + 9x2 + 27x + 27 Given the numbers in the equation, we can likely bet on (x + 3) being a factor. Let's try it with artificial division: 3 * 1 = 3 9 - 3 = 6 3 * 6 = 18 27 - 18 = 9 3 * 9 = 27 27 - 27 = 0 Bingo. So let's carry it out in long division:                       x2 + 6x + 9                    _____________________ x + 3 ) x3 + 9x2 + 27x + 27                        x3 + 3x2                                        6x2 + 27x                                        6x2 + 18x                                                                9x + 27                                                                9x + 27                                                                                    0 So we have: x3 + 9x2 + 27x + 27 = (x + 3)(x2 + 6x + 9) Which we can now factor further with relative ease: = (x + 3)(x + 3)(x + 3) = (x + 3)3
What is 9xsquared equals 2x?
