What are the roots of x3 plus 3x2-9x plus 5?
x3 + 3x2 - 9x + 5 = 0 has roots of -5,1 and 1. CHECK : x3 + 3x2 - 9x + 5 = (x + 5)(x - 1)(x - 1)
How do you solve 3x squared -9x equals 0?
3x2-9x = 0 x(3x-9) = 0 x = 0 or x = 3
How do you factor 3x2 9x3?
To factor the expression 3x^2 - 9x^3, we first need to find the greatest common factor (GCF) of the two terms. The GCF of 3x^2 and 9x^3 is 3x^2. We can factor out 3x^2 from both terms to get 3x^2(1 - 3x). Therefore, the factored form of 3x^2 - 9x^3 is 3x^2(1 - 3x).
What is 9X squared -18X equals to negative 3?
9x2 - 18x = -3x2 - 2x = -1/3x2 - 2x + 1 = 1 - 1/3(x - 1)2 = 2/3x - 1 = ±√2/3x = 1 ± (1/3)√6)
What are the x solutions for the equation 3 x squared minus 42 equals 33?
X = 5 or -5 3x2 - 42 = 33 3x2 = 75 x2=25
How do you factor 3x2-9x?
factor out a 3x 3x(x-3)=3x2-9x
What are the roots of x3 plus 3x2-9x plus 5?
x3 + 3x2 - 9x + 5 = 0 has roots of -5,1 and 1. CHECK : x3 + 3x2 - 9x + 5 = (x + 5)(x - 1)(x - 1)
How do you factor 3x2-9x-912?
3x2 - 9x - 912 = 3(x2 - 3x - 304) = 3(x - 19)(x + 16).
Factor the polynomial 3x2-9x-30?
3x2-9x-30 =3x2+6x-15x-30 =3x(x+2)-15(x+2) =(3x-15)(x+2) OR 3(x - 5)(x+2)
13 Simplify the expression 5x-3x2 9x?
i need help with that question
How do you solve 3x squared -9x equals 0?
3x2-9x = 0 x(3x-9) = 0 x = 0 or x = 3
What is the solution of 3x2-9x equals -5?
3x2 - 9x = -5; add 5 to both sides, in order to use the quadratic formula 3x2 - 9x + 5 = 0; a = 3, b = -9, and c = 5 x = [-b ± √(b2 - 4ac)]/(2a) x = {-(-9) ± √[(-9)2 - 4(3)(5)]}/[(2)(3)] = [9 ± √(81 - 60)]/6 = [9 ± √21)/6
How do you factor 3x2 plus 9x plus 6?
3(x + 1)(x + 2)
What is the x-coordinate of the vertex of the parabola whose equation is y 3x2 9x?
Without an equality sign it can not be considered to be an equation and the - or + value of 9x has not been given
