Question

i) Compare the given quadratic equations to the general form and write values of
a, b&c.
y2 = 5y - 10
If D=0​

Answer 1

GivenQuadraticEquation:2y=10−y

2

\implies y^{2} + 2y = 10⟹y

2

+2y=10

\implies y^{2} + 2y - 10 = 0⟹y

2

+2y−10=0

\begin{gathered}Compare \: above \:equation \: with \\ay^{2} + by + c = 0 ,we \: get \end{gathered}

Compareaboveequationwith

ay

2

+by+c=0,weget

a = 1 , \: b = 2 \: and \: c = -10a=1,b=2andc=−10

Therefore.,

\green { Required \: Equation : y^{2} + 2y - 10 = 0}RequiredEquation:y

2

+2y−10=0

\green { and \: a = 1 , \: b = 2 \: and \: c = -10 }anda=1,b=2andc=−10
