Question

write the discriminant of the quadratic equation (x=5)to power square= 2(5x-3)

Answer 1

Answer:

Discriminant is -124

Step-by-step explanation:

(x-5)^2=2(5x-3)

x^2+25-2×x×5=10x-6

x^2+25-10x=10x-6

x^2-10x+10x+25+6=0

【x^2+0+31】__(|)

compare (|) with ax^2+bx+c

a=1

b=0

c=31

D=b^2-4ac

D=0^2-4×1×31

D=0-124

D=-124.
