Find the roots of the equation by quadratic formula

a= 14 ,b= -45 ,c= -14

b^2-4ac= 2025 + 784
b^2-4ac= 2809
sqrt%282809%29=53

x=%28-b%2B-sqrt%28b%5E2-4ac%29%29%2F%282a%29
x1=%28-b%2Bsqrt%28b%5E2-4ac%29%29%2F%282a%29
x1=%2845%2Bsqrt%282809%29%29%2F%2828%29
x1=(45+ 53)/28
x1=3.5
x2=(45-53)/28
x2= -0.29
