What is the product of a + 3 and –2a2 + 15a + 6 is –2a3 + xa2 + 51a + 18.

x=9

step-by-step explanation:

according to the statement the product of   a + 3 and –2a2 + 15a + 6 is –2a3 + xa2 + 51a + 18.

lets find the product by yourself then solve the question:

(a++15a+6)

multiply each value of bracket 1 by   bracket 2

a(-2a^2+15a+6)+3(-2a^2+15a+6)

-2a^3+15a^2+6a-6a^2+45a+18

now combine the like terms:

-2a^3+9a^251a+18

it is given in the question that the product of   a + 3 and –2a2 + 15a + 6 =       –2a3 + xa2 + 51a + 18.

now compare the both expessions:

-2a^3+9a^251a+18 = –2a3 + xa2 + 51a + 18.

on comparing both sides you will notice that the second term on l.h.s is 9a^2 and the second term on r.h.s is xa^2

therefore x = 9
