Answer:
240^2 - 120x
Step-by-step explanation:
4(2x - 1) x 3 x (2x 5)
4(2x - 1) x 3 x (10x)
4(2x - 1) x 3 x 10x
120x x (2x-1)
240^2 - 120x
Answer:

Hello :
y= <span>x² - 4x + 1
calculate : x
y = (x²-4x+4)-4+1
y+3 = (x-2)²
x exist : if y+3 </span><span>≥ 0
y </span><span>≥ -3
the range is : </span><span>{y: y ≥ -3}</span>
