Question

3 (x+ 2 ) square + 17(x+ 2) + 10​

Answer 1

Answer:

x = -8/3,-7

Step-by-step explanation:

(a+b)²= a²+b²+2ab

0 = 3(x+2)² + 17(x+2) +10

0 = 3x²+12+12x+17x+34+10

0 = 3x²+29x + 56

3* 56= 168,factor for 168 is 21 and 8

0 = 3x² +21x + 8x+56

0= 3x(x+7) + 8(x+7)

3x+8=0----> x= -8/3

x+7 =0 ----> x= -7
