How to factor 3x² -9x - 30 ?

You should take out the common factor of 3 first so it becomes

3(x^2-3x-10)

Then you need two number that multiply to give 10 and can be subtracted to give -3.

These are 2 and -5

The answer is therefore
3(x+2)(x-5)

How do you factor this: 36x^2-120x+100?

Hi,

36x² - 120x + 100 =

4(9x² - 30x + 25) =

4(3x - 5)² <==ANSWER

I hope that helps!! :-)

Solve for x using the factoring method: -30 = 19x - 5x² and 9x² - 30x + 25 = 0 PLEASE CAN U SHOW ME HOW TO DO

-30 = 19x-5x^2
or
5x^2-19x-30 = 0
it is an quardic equation, having two roots or solution
5x^2-25x+6x-30 = 0
5x(x-5)+6(x-5)= 0
(x-5)(5x+6) = 0
either (x-5) = 0
or (5x+6) = 0
if (x-5) = 0
x = 5
or
(5x+6) = 0
x = -6/5

and
9x^2-30x+25 = 0
9x^2-15x-15x+25 = 0
3x(3x-3)-5(3x-5) = 0
(3x-5)(3x-3) = 0
on solving these
x = 5/3
x = 1

How do I factor this equation using decomposition? 6x^2+11x+3

Thank you for the A2A!So, decomposition is a way of factoring that allows us to break apart complex trinomials and make them easier to factor.The first step in decomposition would be, in the form ax^2 +bx +c, find which two numbers add to b, and multiply to a*c.In the case of 6x^2 +11x + 3, we need two numbers that add to 11 and multiply to 18.Quickly cycling through the factors of 18 leaves us with 9 and 2 (multiply to 18, add to 11).From there, we break the middle term into these two parts:6x^2 +11x + 3 becomes:6x^2 + 9x +2x + 3Then, we can factor each half by getting the gcf of the first two terms, and the gcf of the second two terms. 6x^2 + 9x +2x + 3becomes:3x (2x+3) + 1 (2x+3)Which then can be factored again by taking out the 2x+3, giving us a final answer of (3x+1)(2x+3)I really hope this helps! Please let me know if you have any questions!Conner D

Factorize x³-6x² +3x+ 10?

Apply trial and error to the equation by substituting x as any random integer to the equation [math] x^3 - 6x^2 + 3x + 10 = 0 [/math]. If the equation gives a result of 0, then (x - root) will be one factor of the equation.  In that case, consider x = 2, so [math] 2^3 - 6(2)^2 + 3 (2) + 10 = 0 [/math] [math] 8 - 24 + 6 + 10 = 0 [/math]  Hence, (x - 2) is one of the roots of the equation.  Now, apply long division, and accordingly we will obtain another factor as [math] x^2 - 4x - 5 = (x - 5) (x + 1) [/math].  Hence, [math] x^3 - 6x^2 + 3x + 10 = (x + 1) (x - 2) (x - 5) [/math].

Algebra Question: Completely factor 5xsquared -15x-90 which of the following is a factor?

5x^2-15x-90

5(x^2-3x-18)

5(x-6)(x+3)

Without actual division, can you prove that ‘2x^4-6x^3+3x^2+3x-2’ is exactly divisible by ‘x^2-3x+2’?

If P(x)=2x^4–6x^3+3x^2+3x-2 is divisible byg(x)=x^2–3x+2=(x-2)(x-1) thenP(1)=0 and P(2)=0P(1)=2–6+3+3–2=8–8=)P(2)=2×16–6×8+3×4+3×2–2=32–48+12+6–2=50–50=0Therefore P(x) is divisible by g(x).
