Question

find the zeros of which of the following quadratic polynomials and verify the relationship between the zeros and their Coefficient h (t) eq =T square - 15​

Answer 1

Answer:

As below

Step-by-step explanation:

t²-15=0

(t)²-(√15)²=0

{a²-b²=(a+b)(a-b)}

(t+√15)(t-√15)=0

∴t=-√15 or t=-√15

α=-√15 and β=√15

α+β=${\frac{-b}{a}$

√15-√15=0       {Since coeeficient of x does not exist so (-b)=0}

0=0

αβ=$\frac{c}{a}$

(√15)(-√15)=-15

-15=-15

Hence, proved
