x2 + 8x + 15 = (x + 3) (x + 5).
x2+xx = 15 Which is the same as: x2+x2 =15 2x2 = 15 x2 = 7.5 x = the square root of 7.5
3x4 plus 5x3 plus x2 - 5 divided by x 2 =[(3x4) + (5x3) + (x2 - 5)]/x2 =(12 + 15 + x2 -5)/x2 =(27 - 5 + x2)/x2 =(22 + x2)/x2
x2 + 2x - 15 = (x - 3)(x + 5)
x2 + 2x - 15 = (x + 5)(x - 3)
X2+Y3+15 All you can do is simplify it.
x2 + 8x + 15 = (x + 3)(x + 5)
x2 + 8x + 15 = (x + 3) (x + 5).
x2+xx = 15 Which is the same as: x2+x2 =15 2x2 = 15 x2 = 7.5 x = the square root of 7.5
3x4 plus 5x3 plus x2 - 5 divided by x 2 =[(3x4) + (5x3) + (x2 - 5)]/x2 =(12 + 15 + x2 -5)/x2 =(27 - 5 + x2)/x2 =(22 + x2)/x2
x2 + 2x - 15 = (x - 3)(x + 5)
x2 + 2x - 15 = (x + 5)(x - 3)
x2-8x+15 = (x-3)(x-5)
(-4,-1)
x2+2x-15 = (x+5)(x-3) when factored
Break the question down by using Order of Operations. What is x times x? It's X2. What is X2+15? It's X2+15.
x2 + 2x - 15 = x2 - 3x + 5x - 15 = x(x - 3) + 5(x - 3) = (x + 5)(x - 3)
