Solve t^2-3t-6 - ScanMath

Evaluate

t^{2} - 3 t - 6

To find the roots of the expression,set the expression equal to 0

t^{2} - 3 t - 6 = 0

Substitute a= 1,b= - 3 and c= - 6 into the quadratic formula t = \frac{- b \pm b ^{2} - 4 a c}{2 a}

t = \frac{3 \pm ( - 3 ) ^{2} - 4 ( - 6 )}{2}

Simplify the expression

More Steps

t = \frac{3 \pm 33}{2}

Separate the equation into 2 possible cases

t = \frac{3 + 33}{2} t = \frac{3 - 33}{2}

Solution

t_{1} = \frac{3 - 33}{2}, t_{2} = \frac{3 + 33}{2}

Alternative Form

t_{1} \approx - 1.372281, t_{2} \approx 4.372281
