Answer:

The other factor is $(x+2)$

Step-by-step explanation:

we know that

$(x-a)(x-b)=x^{2}-xb-xa+ab$

$(x-a)(x-b)=x^{2}-(a+b)x+ab$

In this problem we have

$x^{2} -8x-20$

and

$a=10$ -----> because is a factor

substitute and solve for b

$x^{2} -8x-20=x^{2}-(10+b)x+10b$

$8=10+b\\b=-2$

Verify in the second equation

$-20=10b$ -----> $-20=10(-2)$ -----> $-20=-20$ --> is ok

The other factor is $(x+2)$

<span>A) x - y = 11
B) 2x +y =19
Multiplying equation A) by -2
A) -2x + 2y = -22 then we add it to B)
B) 2x + y = 19
3y = -3
y = -1
x = 10

$8 \sqrt{3} *4 \sqrt{15} = 8*4 \sqrt{3*15} \\ \\ 32 \sqrt{45} = 32 \sqrt{9*5} =32*3 \sqrt{5} \\ \\ = 96 \sqrt{5}
