Question

Quadratic equation Miscellaneous exercise 10th Quadratic

Answer 1

Answer:

$\sqrt{5} x {}^{2} + 8x - 4 \sqrt{5 }$

$\sqrt{5}x {}^{2} + 8x = 4 \sqrt{5}$

squaring on both sides

Answer 2

√5x^2 + 8x - 4√5= 0

√5x^2 +10x - 2x - 4√5 = 0

√5x ( x + 2√5) - 2 ( x + 2√5)= 0

(x + 2√5)(√5x-2)=0
