Answer:
(2x+3y)(2x-3y)
Step-by-step explanation:
a² - b² = (a + b)(a - b)
4x² - 9y²
= (2x)² - (3y)²
= (2x + 3y)(2x - 3y)
Hello here is a solution :
Answer:
x > 3
Step-by-step explanation:
-17x + 2 < -10x - 19
_____________
.Subtract 2 from both sides.
-17x + 2 - 2 < -10x - 19 - 2
____________________
.Simplify.
-17x < -10x - 21
__________________
.Add 10x to both sides.
-17x + 10x < -10x - 21 + 10x
____________________
.Simplify.
-7x < -21
_________________
.Multiply both sides by -1 (reverse the inequality).
(-7x)(-1) > (-21)(-1)
______________________
.Simplify.
7x > 21
_______________________
.Divide both sides by 7.
7x/7 > 21/7
_____________________
.Simplify.
x > 3
