AB = AC +BC

x + 8 = 2x -5 + (BD + DC)

x + 8 = 2x-5 + 10 +14

x + 8 = 2x + 19

2x - x = -19 + 8

Which shows one way to determine the factors of 12x3 – 2x2 18x – 3 by grouping?.
Ksenya-84 [330]

The equation which shows the one way to determine the factors of provided equation by grouping is,

2x^2(6x-1)+3(6x-1)

<h3>What is a factor of polynomial?</h3>

Polynomial equations is the expression in which the highest power of the unknown variable is n (n is real number).

Factor of a polynomial is the terms in linear form, which are when multiplied together, give the original polynomial equation as result.

The provided polynomial equation is,

12x^3 - 2x^2 +18x - 3

To factorize the above polynomial equation, make the groups, by taking out the greatest common factor.

12x^3 - 2x^2 +18x - 3\\2x^2(6x-1)+3(6x-1)\\(6x-1)(2x^2+3)

Hence, the equation which shows the one way to determine the factors of provided equation by grouping is,

2x^2(6x-1)+3(6x-1)

32.16 / 6 = 5.3583333.... rounded it would be

5.35

2) The cost of 7 pounds would be 103.18

73.70 / 5 = 14.74 (cost of one pound)

14.74 x 7 = 103.18
