What is 3x2 - 4x - 4?
It is a quadratic expression and is (3x+2)(x-2) when factored
How do you subtract binomials and monomials?
It depends on what you wish to subtract them from. The solution is to write the minuend (what you want to subtract FROM). Then append the binomial or monomial with the sign of each term changed. Then combine like terms.For example, if you wish to subtract 3x2 - 4x + 6 from sin(x) + 5x, the solution issin(x) + 5x - 3x2 + 4x - 6 = sin(x) + x - 3x2 - 6
When x3 plus 3x2-2x plus 7 is divided by x plus 1 what is the remainder?
(x3 + 3x2 - 2x + 7)/(x + 1) = x2 + 2x - 4 + 11/(x + 1)(multiply x + 1 by x2, and subtract the product from the dividend)1. x2(x + 1) = x3 + x22. (x3 + 3x2 - 2x + 7) - (x3 + x2) = x3 + 3x2 - 2x + 7 - x3 - x2 = 2x2 - 2x + 7(multiply x + 1 by 2x, and subtract the product from 2x2 - 2x + 7)1. 2x(x + 1) = 2x2 + 2x2. (2x2 - 2x + 7) - (2x2 + 2x) = 2x2 - 2x + 7 - 2x2 - 2x = -4x + 7(multiply x + 1 by -4, and subtract the product from -4x + 7)1. -4(x + 1) = -4x - 42. -4x + 7 - (-4x - 4) = -4x + 7 + 4x + 4 = 11(remainder)
What is 3x2-4x plus 7 when x equals -2?
3x2= 6 6-(4x-2)= 6--8= 6+8 = 14 14+7 = 21
What is the degree of this polynomial 3x2-4x 9?
It is of the 2nd degree.
Does 3x2-4x factor?
x(3x-4)
What is 4x plus 3x squared?
3x2 + 4x factors to x(3x + 4)
Simplify 3x2 plus 2x - 8?
3x2 + 2x - 8 = 3x2 + 6x - 4x - 8 = 3x(x + 2) - 4(x + 2) = (x + 2)(3x - 4).
Which of the binomials below is a factor of this trinomial X2 plus 4x-32?
(x - 4) or (x + 8)
How do you factor x3 plus 3x2-4x-12?
x3 + 3x2 - 4x -12 x2(x + 3) - 4(x + 3) (x2 - 4)(x+3)
What is 3x2 - 4x - 4?
It is a quadratic expression and is (3x+2)(x-2) when factored
Factor this polynomial completely 3x2 plus 2x - 8?
3x2 + 2x - 8 = 3x2 + 6x - 4x - 8 = 3x(x+2) - 4(x+2) = (3x-4)*(x+2)
State the discriminant of the quadratic 3x2-4x plus 4 equals 0?
The discriminant is -32.
3x2 plus 4x-15 equals 0?
no 3x2=6 then 4x-15= -60 so 6 added with - 60 = -54
3X2 plus 4X plus 1 equals?
3x2 + 4x + 1 = ?? This is a quadratic equation. The equation can be made to equal any number and this will determine the corresponding values of x. EXAMPLE : 3x2 + 4x + 1 = 96 (x = 5 or x = -19/3) Alternatively, if x is known then this will determine the result. EXAMPLE : If x = 2 then (3 x 4) + (4 x 2) + 1 = 12 + 8 + 1 = 21 In normal use, a quadratic equation is presented as equal to zero. In this example : 3x2 + 4x + 1 = 0
