Answer 1

y= x² - 3x - 3 → ( in standard form )

factor the quadratic to obtain intercept form

the factors of - 3 which sum to - 2 are - 3 and + 1

y = (x - 3)(x + 1) → ( in intercept form )

for vertex form use ' completing the square '

y = x² + 2( -1 )x + ( - 1 )² - ( - 1 )² = ( x - 1 )² - 4

y = ( x - 1 )² - 4 → ( in vertex form )
