Convert to intercept form (hint: factor completely, GROUPING)

y = 2x³ + 7x² - 2x - 7

• cannot be factored

• y =(x - 1)²(2x + 7)

• y=(x² - 1)(2x + 7)

• y=(x + 1)(x - 1)(2x + 7)

convert from factored from to standard

y= (x+2)(x+5)(x-3)

• y= x³+ 6x² -11x +30

• y= x³ - 30

• y=x³+4x²-11x-30

• y= 3x³+10x²-15
