use the FOIL system First, Outside, Inside, Last. when you see this (x -2)(5x -7) multiply the numbers that appear first in each system. in this case x and 5x. When multiplying variables simply raise the power. x times 5x = 5x^2. Then you multiply the two outside numbers in this case x and -7. which equals -7x. Then the inside numbers in the same manner. -2 and 5x equals -10x. and then the numbers that appear last in each system. -7 and -2 which equals +14. Finally add all the terms. 5x^2 + -10x + -7x + 14 = 5x^2 -17x +14

Is The factors of x2 are x and x - 5?
The factors of x2 are x and x.
Can you factor out exponents?
You sure can, here is an example I made up to show you: x4+x2= x2(x2+x) When you factor it out it should look like this because if you multiply it back up (where the exponents will multiply not add) it will equal the primary equation.
What are the factors of x2 - 5x plus 6?
x2 - 5x + 6 = (x - 2)(x - 3)
What are the factors of x2 9x-36?
x2+9x-36 = (x-3)(x+12) when factored
What are the factors of x2 equals -11x-10?
x2 = -11x - 10 x2 + 11x + 10 = 0 (x + 1)(x + 10) = 0
What are the factors of x2-x-20 and why?
The factors of x2 - x - 20 are (x - 5) and (x + 4) because when you multiply them together, they come out to x2 - x - 20.
Factor out the GCF -13x2 - 5x7?
-x2(5x5 + 13)
What numbers can you multiply to get 35?
You can multiply 5 and 7 to get to 35. (5x7=35)
How do you figure the product of the numbers 5 and 7?
Multiply it, adah 5X7= 35
Is The factors of x2 are x and x - 5?
The factors of x2 are x and x.
x2+x-6 over x2-x-2 (fraction) multiply by x2+11x+24 over x2-x-2 (fraction) divide by x+3 over x2+3x+2.multiply and divide as indicated. please help?

Are the factors of x2 are x and x plus 1?
The factors of x2 are x and x x times x plus 1 = x2 + x
What is the factorization of the trinomial below. -x2 - 2x plus 48?
First, I'll multiply by -1, to make it a little easier to work with (then when done, I'll multiply by -1 again): x2 + 2x - 48. We want two numbers, when multiplied yield -48, and the sum is 2: -6 and 8. (x + 8)(x - 6) works. Now multiply one of the binomial factors by -1: (x + 8)(6 - x). Multiply using FOIL to check: -x2 - 2x + 48
What is the factor of the polynomial in descending order x2 plus 7x plus 10?
Restate the question: Factor the polynomial x2 + 7x + 10. You look for two numbers which multiply to make 10 and add to make 7. They are 5 and 2. Now put them into the two factors: (x + 5)(x + 2). Check your factors by multiplying using 'FOIL': x2 + 2x + 5x + 10 = x2 + 7x + 10. Check!
What is the distributive property to multiply 5 x 607?
(5x600) + (5x7)= 3035 3000 + 35 = 3035
How can you factor x2-13 plus 30?
x2 - 13 + 30 = x2 + 17, which has no real factors.
How to factor x2-3x 9 over 4?
Multiply by 4. 4x2 - 12x + 9 factors to (2x - 3)(2x - 3) or (2x - 3)2
