Question

Please Help for medal:

Solve: x^2-3x-10=0

Answer 1

"Factor the equation to
(x - 5)(x + 2) = 0

Set both factors equal to 0
x - 5 = 0
x + 2 = 0

Solve for x and the answer is
x = 5
x = -2"

Does that help?

Answer 2

\[x ^{2} - 3x - 10 = 0\]
Factor each out into two paranthetical sub groups
(x - 5)(x + 2) = 0
Set both groups = to 0. Solve for x

Answer 3

\[\huge x^2-3x-10=0 \rightarrow x^2-5x+2x-10=0\]
\[\huge \rightarrow x(x-5)+2(x-5)=0\]
\[\huge \rightarrow (x+2)(x-5)=0\]
\[\huge \rightarrow (x+2)=0 ---or ---(x-5)=0\]
\[\huge \rightarrow x=-2 ---or ---x=5\]
Hence x= -2, 5 are the required solutions
