X2 plus 3x plus 3 equals 7?
x2 + 3x + 3 = 7Subtract 7 from each side:x2 + 3x - 4 = 0Factor the left side:(x + 4) (x - 1) = 0x = - 4x = +1
How do you factorise x2 plus 2-15?
x2 + 2x - 15 = x2 - 3x + 5x - 15 = x(x - 3) + 5(x - 3) = (x + 5)(x - 3)
X2 plus 3x plus 7 equals 5?
x2 + 3x + 7 = 5 ∴ x2 + 3x + 2 = 0 ∴ (x + 1)(x + 2) = 0 ∴ x ∈ {-2, -1}
