Question

(2x + 3)(x - 5)(x квадрат - 10) = 0
Help me.

Answer 1

Ответ:

- √10; - 1,5; √10; 5.

Объяснение:

(2x + 3)(x - 5)(x^2- 10) = 0

2x+3=0 или x - 5= 0, или x^2- 10= 0

1. 2х + 3 = 0

2х = - 3

х = - 3: 2

х = - 1,5

2. х - 5 = 0

х = 5.

3. x^2- 10= 0

x^2= 10

х = ±√10

Ответ: - √10; - 1,5; √10; 5.

Answer 2

$(2x+3)(x-5)(x^{2} -10)=0\\\\1)2x+3=0\\\\2x=-3\\\\x_{1} =-1,5\\\\2)x-5=0\\\\x_{2}=5\\\\3)x^{2}-10=0\\\\(x-\sqrt{10})(x+\sqrt{10})=0\\\\x-\sqrt{10}=0\\\\x_{3}=\sqrt{10} \\\\x+\sqrt{10}=0\\\\x_{4}=-\sqrt{10} \\\\Otvet:\boxed{-\sqrt{10};-1,5;\sqrt{10};5}$
