Solve by factorising x2 + 8x + 15 0
WebThis is then the final solution: x=3 or x=5. We can check these answers by subsitituting these values for x back into the equation to ensure that we get the correct result. For x=3 the equation becomes (3 * 3) - (8 * 3) +15 = 9 - 24 + 15 = 0 which is correct. For x=5 the equation becomes (5 5) - (8 5) + 15 = 25 - 40 +15 = 0 which also solves ...
