Question

(x+5)² = 2(5x-3) write the discriminate of the quadratic equation

Answer 1

ANSWER❣❣↙️↙️

(X+5)^2=2(5X-3)

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

X^2+25+6=0

X^2+31

X=$\sqrt{ - 31}$

HOPE IT HELPS YOU✨✨✌✌

Answer 2

$\huge {Solution}$

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

By using ....

$( {(a + b)}^{2} = {a}^{2} + {b}^{2} + 2ab)$

$= {x}^{2} + {5}^{2} + 2 \times x \times 5 = 10x - 6$

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

$= {x}^{2} + 25 + 10x - 10x + 6 = 0$

$= {x}^{2} + 31 = 0$

$= x = \sqrt{31}$
