Question

x2+10x+4=15
How do I show my work for this problem and get my answer?

Answer 1

Step-by-step explanation:

$\implies$ $\sf{ x^2+10x+4=15}$

$\implies$ $\sf{x^2+10x+4-15=0 }$

$\implies$ $\sf{x^2+10x-11=0 }$

$\implies$ $\sf{x^2+11x-1x-11=0 }$

$\implies$ $\sf{x(x+11)-1(x+11)=0 }$

$\implies$ $\sf{(x+11)(x-1)=0 }$

$\implies$ $\boxed{\sf{x=-11\:or\:x=+1 }}$
