Answer:

[tex]x^2-15x+56[/tex]

Step-by-step explanation:

Use the FOIL distributive method: [tex]\left(a+b\right)\left(c+d\right)=ac+ad+bc+bd[/tex]

---------------------------------------------------------------------------------------------

Thus, [tex]\left(x-7\right)\left(x-8\right)=x\times x +x\left(-8\right)+\left(-7\right)x+\left(-7\right)\left(-8\right)[/tex]

Multiply them to get:

[tex]x^2-8x-7x+56[/tex]

[tex]x^2-15x+56[/tex]
