Question

find the roots of the quadratic equations by factorization x^2-4√3x-15​

Answer 1

Answer:

find the roots of the quadratic equations by factorization x^2-4√3x-15​

Step-by-step explanation:

$x^2-4\sqrt3x-15\\=x^2-5\sqrt3x+\sqrt3x-15\\=x(x-5\sqrt3)+\sqrt3(x-5\sqrt3)\\=(x-5\sqrt3)(x+\sqrt3)$
