Step-by-step explanation:
Answer:
4(5x - 3y)(5x + 3y)
Step-by-step explanation:
Assuming you require the expression factored.
Given
100x² - 36y² ← factor out 4 from each term
= 4(25x² - 9y²) ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , thus
25x² - 9y²
= (5x)² - (3y)² ← with a = 5x and b = 3y
= (5x - 3y)(5x + 3y)
Thus
100x² - 36y² = 4(5x - 3y)(5x + 3y) ← in factored form
Answer:
7
Step-by-step explanation:
5( x - 3)/2 - 1 = 9
5/2(x-3)-1=9
5/2x-15/2-1=9
5x-15-2=18
5x-17=18
5x=35
x=7
