Question

Which of the following are solutions to the equation below? Check all that apply. x2 + 3x - 10 = 0

Answer 1

Answer:

Options B and F.

Step-by-step explanation:

$x^2 + 3x - 10 = 0$

$(x-2)(x+5)=0$

$x-2=0\\x=2$

$x+5=0\\x=-5$

Answer 2

Answer:

x = 2

x = -5

Step-by-step explanation:

$x^{2} + 3x - 10 = 0\\a *c = 1*-10=-10\\Find-factors-when-they- are -added= 3x -and-when-multiplied=-10\\Factors = -2x, and 5x\\x^{2} -2x+5x-10=0\\x(x-2)+5(x-2)=0\\(x-2)(x+5)=0\\(x-2)=0 ,or, (x+5)=0\\x = 0+2 , or, x =0-5\\x = 2 \\x =- 5$
