Question

2. Write the equation x2 - 8 = 15 in the form of ax2 + bx + c = 0, then write the values of a, b, c .​

Answer 1

answer is 0

Step-by-step explanation:

x2-8=15

x2=15+8=23

x=23/2

x=11.5

as given.

ax2+bx+c= 0 substution

x=11.5

a×11.5×2+b×11.5+c=0

a×23+b+c=0÷11.5=0

a+b+c=0÷23=0

a=0

b=0

c=0
