How do you factor 7x2-31x-20?
(7x + 4)(x - 5)
How do you solve the quadratic equation 7x2-5x equals 0 by factoring?
if the x in "7x2" is variable x, then 7x(2)-5x=0 14x-5x=0 9x=0 x=0 if the x in "7x2" is a symbol for multiplication, then 7(2)-5x=0 14-5x=0 -5x= -14 5x=14 x= 14/5 x= 2 4/5 or, to factor it out... x(14-5)=0 x(9)=0 9x=0
What are the common factors of 14 and 49?
The common factors of 14 and 49 are 1 and 7.1x49=49 1x14=147x7=49 7x2=14 1 and 7
How do you write a power as a product?
The exponent tells how many times the base is used as a factor. 23 = 2 x 2 x 2
How do you factor 7x2 - 9x - 10?
Factor 7x2 - 9x - 10 = 0.7 * -10 = -7070 = 2 * 35 = 2 * 5 * 7Factors of 70: 1,2,5,7,10,14,35,701 x 70 = 702 x 35 = 705 x 14 = 707 x 10 = 70The sum should be negative, so the larger number in the sum must be negative.product of -70 (sum of -9) :1 + (-70) = -692 + (-35) = -335 + (-14) = -97 + (-10) = -3The sums match up, so now we have the factors.(x+5)(x+(-14)) = 0(x+5)(x-14) = 0However, the x2 must have a 7 in front of it, so divide the 14 by 7.(7x+5)(x-2) = 0And, if you have extra time, you can foil it back out to make sure you did it correctly.7x2 - 14x + 5x -10 = 07x2 - 9x - 10 = 0This confirms that the factorization is correct.Finally, if you want to solve for x, just set each term equal to zero.7x+5 = 0 or x-2 = 07x = -5 or x = 2x = -5/7 or 2
What is the greatest common factor of 35x6 and 7x2?
You can take 7x2 out of both of those, leaving 5x4 and 1.
What is the greatest common factor of 7x2 plus 49x5-37x2z?
The GCF is x2
Factor the polynomial 7x2 plus 68xy - 20y2?
7x2 + 68xy - 20y2
Are 14 and 35 both divisible?

How do you factor 28x3-7x2 plus 36x-9?
(7x2 + 9)(4x - 1)
How do you factor 7x2 49?
7(x2 + 7)
How do you simplify 7x2 - 9x - 10?
I suppose you mean, how do you factor it. 7x2 - 9x - 10 = (7x + 5)(x - 2).
What is the Examples of common monomial factor?
1. 3x2+12= 3(x2+4) 2. 7x2+35x= 7x(x+5)
How do you factor 14x squared minus 7x to the 3rd power?
I suppose that would be 14x2 - 7x3. Just take out the common factor, 7x2. Divide each term by this factor to find the other factor.
What is the factor of 7x2-19x-6?
(x - 3)(7x + 2)
How do you factor 7x2-31x-20?
(7x + 4)(x - 5)
