Answer 2

The simplified form is $x^2-2x$.

Step-by-step explanation:

Consider the provided expression.

$(x+5)(x-7)+35$

Apply the FOIL method: $\left(a+b\right)\left(c+d\right)=ac+ad+bc+bd$

Apply the above rule and simplify the expression.

$x\cdot x+x\cdot(-7)+5\cdot x+5\times(-7)+35$

$x^2-7x+5x-35+35$

$x^2-7x+5x$

$x^2-2x$

Hence, the simplified form is $x^2-2x$.
