What is the answer for m^2-5m-14=0?
tensa zangetsu [6.8K]

Answer: m = 7 or -2

Step-by-step explanation:

Quadratic Formula!  \frac{{-b (+/-)\sqrt{(b^{2}-4ac }}}{2a}

Polynomial Form: ax^{2} +bx+c

So in this example a: 1  b: -5  c: -14

You get:\frac{{-(-5) (+/-)\sqrt{((-5)^{2}-4(1)(-14) }}}{2(1)}

m = 7 or -2

Check by plugging a value back in for m

(7)^{2} -5(7)-14=0?\\(-2)^{2} -5(-2)-14=0?\\

True for both.
