Answer:
3 3/4
Step-by-step explanation:
(4x+3)(x-8)+(x-1)(4x+3)=0
Factor out 4x+3
(4x+3)( x-8+x-1) =0
Combine terms
(4x+3) ( 2x-9) =0
Using the zero product property
4x+3 = 0 2x-9 =0
4x=-3 2x = 9
x = -3/4 x = 9/2
Sum the solutions
-3/4 + 9/2
-3/4 + 18/4
15/4
3 3/4

Hi again :)
5b^3(4 - 9b^2)
Use the distributive property
=(5b^3)(4) + (5b^3)(-9b^2)
= 20b^3 - 45b^5
= -45b^5 + 20b^3
Have a nice day!
