In the case of 4x%5E2%2B7x%2B2, which is in the form ax%5E2%2Bbx%2Bc=0, we can see that a = 4, b = 7, c = 2

Plug this into the formula below

x+=+%28-b%2B-sqrt%28b%5E2-4ac%29%29%2F%282a%29

x+=+%28-%287%29%2B-sqrt%28%287%29%5E2-4%284%29%282%29%29%29%2F%282%284%29%29

x+=+%28-7%2B-sqrt%2849-%2832%29%29%29%2F%288%29

x+=+%28-7%2B-sqrt%2817%29%29%2F8

x+=+%28-7%2Bsqrt%2817%29%29%2F8 or x+=+%28-7-sqrt%2817%29%29%2F8

x+=+-0.359611796797792 or x+=+-1.39038820320221

So the exact solutions are x+=+%28-7%2Bsqrt%2817%29%29%2F8 or x+=+%28-7-sqrt%2817%29%29%2F8

and the approximate solutions are x+=+-0.359611796797792 or x+=+-1.39038820320221
