Step-by-step explanation:
5x(2x - 7) = 0
standard form
10x² - 35x = 0
value of x1
5x = 0
5x/5 = 0/5
x = 0
value of x2
2x - 7 = 0
2x = 7
2x/2 = 7/2
x = 7/2
check x1 = 0
5(0) (2(0) - 7) = 0
0(-7) = 0
0 = 0
check x2 = 7/2
5(7/2) [2(7/2) - 7] = 0
35/2 (7 - 7) = 0
35/2 (0) = 0
Answer:
10x²-35x
I'm not sure...
