Answer:
[tex]-\left(x+7\right)\left(x+8\right)[/tex]
Step-by-step explanation:
[tex]-X^2-15x - 56\\\\\mathrm{Factor\:out\:common\:term\:}-1\\\\=-\left(x^2+15x+56\right)\\\\=-\left(x+7\right)\left(x+8\right)[/tex]
Answer:
[tex]-(x+7) (x+8)[/tex]
Step-by-step explanation:
[tex]-x^{2} - 15x-56[/tex]
Write - 15x as a difference
[tex]-x^{2} -7x-8x-56[/tex]
Factor out - x from the expression
[tex]-x(x+7)-8x-56[/tex]
Factor out - 8 from the expression
[tex]-x (x+7)-8(x+7)[/tex]
Factor out - (x + 7) from the expression
[tex]-(x+7)x(x+8)[/tex]
