Question

y²=7y Compare the given quadratic equation to the general form and write values of a, b, c.

Answer 1

Quadratic equation : An equation of degree 2 is called a quadratic equation.

General form of Quadratic equation :

ay² + by+ c , where a,b,c are constants and a≠0.

SOLUTION:

GIVEN : Y²=7y

y² -7y = 0

On comparing with General form of Quadratic equation : ay² + by+ c = 0

Here, a= 1, b = -7 , c = 0.

Hence , the value of a= 1,b = -7 & c = 0

Answer 2

we know, general form of quadratic equation is given ay² + by + c = 0 , coefficient of y² = a
coefficient of y = b , constant = c

here, given,
y² = 7y
y² - 7y + 0 = 0
compare with ay² + by + c = 0
a = 7 , b = -7 and c = 0

y² = 7y
=> y² - 7y = 0
=> y(y - 7) = 0
=> y = 0 and 7
hence, roots of y² - 7y are 0 and 7
