Which are the solutions of x2 = –11x + 4?
Zarrin [17]

For this case we have the following polynomial:

x ^ 2 = -11x + 4

Rewriting the polynomial we have:

x ^ 2 + 11x - 4 = 0

From here, we can solve the polynomial using the quadratic equation

We have then:

x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}

x=\frac{-11+/-\sqrt{11^2-4(1)(-4)}}{2(1)}

x=\frac{-11+/-\sqrt{11^2+16}}{2}

x=\frac{-11+/-\sqrt{121+16}}{2}

x=\frac{-11+/-\sqrt{137}}{2}

Therefore, the solutions are:

x=\frac{-11+\sqrt{137}}{2}

x=\frac{-11-\sqrt{137}}{2}
