# 3x squared minus x minus 2?

What is the question? Do you want to factor 3x2 -x -2? If that is the question the answer is (3x + 2)(x-1)

# How do you solve x squared minus 3x 10?

X squared - 3x - 10 = 0 (x-5) (x+2) = 0 x - 5 = 0 x + 2 = 0 X= 5 x = -2

# Factor x cubed plus x squared minus 3x minus 3?

x³ + x² - 3x - 3 = (x + 1)(x + √3) (x - √3).

# What is 3x squared minus x squared?

3x^2 - x^2 = (3 - 1)(x^2) = 2x^2 It is a good idea early one in math to think of things like this.. just like we can add or subtract numbers, we can add or sub…tracts x^2 or x^3 or squareroots of x... So think of 3x^2 as three (x^2)s...that is to say x^2 is something, like apples or oranges and you are just taking 3 or them and taking away one of them, so you have 2 of them.

# What is Factor x squared plus 3x minus 54?

(x - 6)(x + 9)

# X squared minus 3x plus 5?

This quadratic expression cannot be factored because its discriminant is less than zero.

# How do you factor x squared minus 3x minus 40?

(x - 8)(x + 5)

# How do you factor 3x cubed x squared minus 25?

well, i believe it goes like this (not certain) 25 is the only not prime number so... 3xcubed x squared -5 squared

# What is x squared minus 3x minus 28 for x?

This expression doesn't tell what 'x' has to be. In fact, 'x' can be anything. Your choice. Every time you change 'x', the expression becomes a different number. If this e…xpression were equal to something, then we could get some exercise figuring out what 'x' must be in order to make the equation true. But in its present form, it doesn't say anything, so there's nothing to be proven true or false. It's just a number that depends on what 'x' is.

# What is 3x squared minus 4 if x is 3?

3x2 -4 (x=3) 3(32)-4 3(9)-4 27-4=23

# How do you solve 3x squared plus x minus 14?

Do you mean: 3x2+x-14 = 0 If so the solutions are: x = 2 and x = -7/3 using the quadratic equation formula

# What are the factors of 3x squared minus x plus 4?

That doesn't factor neatly. Applying the quadratic equation, we find two imaginary solutions: (1 plus or minus the square root of -47) divided by 6. x = 0.16666 + 1.14260910…0066840i = 1st root = r1 x = 0.16666 - 1.142609100066840i = 2nd root = r2 where i is the square root of negative one. Then factor as (x - r1)(x - r2) Or you can complete the square to transform the trinomial into the difference of the squares 3x2 - x + 4 factor out 3 = 3(x2 -(1/3)x + 4/3) add and subtract (1/6)2 = 3[x2 -(1/3)x + (1/6)2 - 1/36 + 4/3] simplify = 3[(x - 1/6)2 + 47/36] write 47/36 = - (-47/36) = - (√-1√47/6)2 = - (i√47/6)2 = 3[(x - 1/6)2 - (i√47/6)2] write the difference of the squares = 3[(x - 1/6) - (i√47/6)][(x - 1/6) + (i√47/6)] = 3[(x - (1 + i√47)/6)][(x - (1 - i√47)/6].
