Answer:

4x^2+19x-47

Step-by-step explanation:

(4x^2+8x+15)+(x^2-x-27)-(x-5)(x-7)

=(4x^2+8x+15)+(x^2-x-27)-x^2+7x+5x-35

=(4x^2+x^2-x^2) + (8x-x+7x+5x) + (15-27-35)

= 4x^2+19x-47

Hope this helps!

Solve for the indicated variable

GrogVix [38]

Answer:

$X_1=\frac{YX_2}{X_2-Y} \\\\$

Step-by-step explanation:

$\frac{1}{Y}=\frac{1}{X_1}+\frac{1}{X_2}$

First subtract the 1/x2

$\frac{1}{Y} - \frac{1}{X_2}=\frac{1}{X_1}$

Next subtract the fractions on the left

$\frac{X_2-Y}{YX_2}=\frac{1}{X_1}\\$

Next Multiply by x1

$\frac{(X_1)X_2-Y}{YX_2}=1\\$

Next divide both sides by the remaining parts (not x1)

$X_1=\frac{YX_2}{X_2-Y} \\\\$
