checking problem
Use FOIL to multiply:
(6x – 1)(3x – 4)
6x*3x + 6x*(-4) + (-1)*3x + (-1)*(-4) =
6x*3x = 18x^2
6x*-4 = -24x
-1*3x = -3x
-1* -4 = 4
18x^2 – 24x -3x +4 =
18x^2 – 27x + 4
Thats right! :)
Thankyou.
Any insight on this next one?
(x^4y^6z^12/9^-2x^3y^-8z^-9)^0
I am not sure why but i get the answer
1/9^0
I was thinking the ^0 multiplies everything to 0 but the 9.
John,
(anything) = 1 except 0^0 which is undefined
Anything to the 0 power is 1. And somehow my final answer was
xz^3 / 9^-2y^-2
but i really could be wrong, hopefully someone else can help u with this one cause im not positive!
6xy/9y4x30x3y/-48x
-5(x+1)+3x+2=6x+4
To multiply using FOIL, follow these steps:
1. Write out the two binomial expressions side by side, like this: (6x - 1)(3x - 4).
2. Begin with the first terms of each binomial and multiply them together. In this case, it is 6x * 3x = 18x^2.
3. Next, multiply the outer terms. Multiply the first term of the first binomial with the last term of the second binomial: 6x * -4 = -24x.
4. Then, multiply the inner terms. Multiply the last term of the first binomial with the first term of the second binomial: -1 * 3x = -3x.
5. Lastly, multiply the last terms of each binomial: -1 * -4 = 4.
Now, combine all the terms together:
18x^2 - 24x - 3x + 4
Simplify like terms by combining the x terms: -24x - 3x = -27x.
The final result is:
18x^2 - 27x + 4.
So, the product of (6x - 1)(3x - 4) using FOIL is 18x^2 - 27x + 4.
