Answer this correctly

Question

Match the equation on the left to its equivalent on the right.

y = x^2 + 6x + 5 blank
y = (x + 7)(x - 4) blank
y = x^2 - 7x + 12 blank
y = (x+4)^2 - 7 blank

1. y = x^2 + 3x - 28
2. y = (x - 3)(x - 4)
3. y = (x + 3)^2 - 4
4. y = x^2 + 8x + 9

Answer 1

y = x^2 + 6x + 5 : y = x^2 + 3x - 28
y = (x + 7)(x - 4) : y = (x - 3)(x - 4)
y = x^2 - 7x + 12 : y = x^2 + 8x + 9
y = (x+4)^2 - 7 : y = (x + 3)^2 - 4
