Answer:
b is 0
Step-by-step explanation:
yes, i am here :)
Step-by-step explanation:
a) 2x(3x + 1)(4 - 2x) = 0
=> 2x = 0 (or) 3x + 1 = 0 (or) 4 - 2x = 0
=> x = 0 (or) x = -1/3 (or) x = 2
b) x²(2x + 1)(x - 3) = 0
=> x²=0 (or) 2x + 1=0 (or) x - 3=0
=> x = 0 (or) x = -1/2 (or) x = 3
Hope you've understood the solutions.
