Consider the factors of the constant term which sum to give the coefficient of the x- term
13
x² - x - 42 = (x - 7)(x + 6)
15
x² + x - 6 = (x + 3)(x - 2)
17
x² - 27x + 50 = (x - 25)(x - 2)
19
r² - 25 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , thus
r² - 25
= r² - 5² = (r - 5)(r + 5)
180=(9X-11)+(4X+1)+(7X-3)
180=20x-13
193=20x
9.65=x
Polynomials are set of expressions with variables that are usually used in operations.
*2x^2 +3x-2
2x^4+3x^3(2x^3+2x)=4x^7+4x^5+6x^6+6x^4
*(^ is the raised exponent)
