I think you would distribute what is in the parentheses and then make it so only a and b are on the left and i and the other characters that can be simplified are on the left but feel free to Google it.
X intercept is when y = 0
3x -15(0) = 60
3x = 60
x = 20
y intercept is when x=0
3(0) -15y = 60
-15y = 60
y = -4
Answer is C
Answer:

Step-by-step explanation:
Given
x² - 3x
To make the expression a perfect square
add ( half the coefficient of the x- term )²
x² + 2( -
)x +
, thus
x² - 3x + 
= (x -
)² ← a perfect square
Now you see when you use a model it is harder kepause........
