Question

find by inspection the coefficient of x in (x+17)(x+2)​

Answer 1

19

Given mathematical expression:

(x+17)(x+2)

Asked: Coefficient of x.

when we simplify by multiplying

$x^2+2x+17x+34$

$=x^2+19x+34$

we observe that such a case where we have to multiply two binomials in the same unknown variable and a constant with it then we obtain a 2-degree trinomial in which coefficient of 1-degree variable is the sum of constants (with their sign) in the binomials being multiplied.
