Question

Write the discriminant of quadratic equation (x+5)^2=2(5x-3)

Answer 1

$2x + 10 = 10x - 6 \\ 2x - 10x = - 10 - 6 \ \\ - 8x = - 4 \\ x = \frac{8}{4} = 2$

divide 8 by 4

ans , quadrilateral equation is x =2

Answer 2

Answer:

Discriminant of the quadratic equation is D=-124.

Step-by-step explanation:

Given the quadratic equation

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

we have to write the discriminant of the quadratic equation

The quadratic equation,

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

$x^2+5^2+2(x)(5)=10x-6$

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

$x^2+31=0$

Comparing above equation with general form of quadratic equation, $ax^2+bx+c=0$

a=1, b=0, c=31

$Discriminant=b^2-4ac$

$=0^2-4(1)(31)=-124$

Therefore, discriminant of the quadratic equation is D=-124.
