Answer:

8x² + 8

Step-by-step explanation:

Given

(x² + 3)² - (x² - 1)² ← expand both factors using FOIL

= x^{4} + 6x² + 9 - (x^{4} - 2x² + 1) ← distribute by - 1

= x^{4} + 6x² + 9 - x^{4} + 2x² - 1 ← collect like terms

= 8x² + 8

Solve for the variable 7/28 = 25/?
ICE Princess25 [194]
Let x be the unknown number. The equation is going to be 7/28=25/x, now we cross multiply. 7*x=25*28, 7x=700, divide both sides by 7 and you should get 100, So, x=100 and 7/28=25/100
