Question

Isabella is solving the equation 4x2 = 13x – 3 with the quadratic formula.

What values should she use for a, b, and c?


a. a = 4
b= 13
c = –3


b. a= 4
b = –13
c = 3


c. a = 4
b = –3
c = 13


d. a = 4
b = 3
c = –13

Answer 1

2nd answer
4x^2-13x+3
Bring the 13,3 to the left

Answer 2

we know,
standard form of quadratic equation,
ax² + bx + c =0-----------(1)

here given ,

4x² = 13x -3
4x² -13x +3 =0 -----------(2)

compare both the equations ,
then ,
a = 4
b = -13
c = 3

hence, option ( b) is correct
