●i hope its help●
An equation of degree 2 is called a quadratic equation.
General form of Quadratic equation :
ax² + bx + c , where a,b,c are constants and a≠0.
GIVEN : x² - 9=13
x² -9 -13 = 0
x² -22 = 0
comparing with General form of Quadratic equation : ax² + bx + c = 0
Here, a= 1, b = 0 , c = -22
Hence , the value of a = 1, b = 0, c = -22
HOPE THIS WILL HELP YOU...
1 First OPTION Is Correct
a= 1 b= -7 c=5
using ax²+bx+c = 0
3m² = 2m² - 9
In standard form
m² + 0m + 9 = 0
So, a = 1, b = 0, and c = 9
yes nice question
