There is a formula for the "difference of squares." In this case, the answer is (5x + 3)(5x - 3)
11x + 2
x= -11
7X-1=9+5X. add 1 to both sides 7X=10+5X. Subtract 5X and get 2X=10 divide by 2 and x=5

Without the inclusion of an equality sign and not knowing the plus or minus values of the given terms it can't be considered to be a straight line equation
5x² - 18x + 9 = (5x² - 15x) - (3x - 9) = 5x(x - 3) - 3(x - 3) = (5x - 3)(x - 3).
X= 2!
There is a formula for the "difference of squares." In this case, the answer is (5x + 3)(5x - 3)
11x + 2
x= -11
3x + 9 = 5x - 43x +13 = 5x13 = 2x13/2 = xso x = 6.5
7X-1=9+5X. add 1 to both sides 7X=10+5X. Subtract 5X and get 2X=10 divide by 2 and x=5
10x - 5x + 5x = 10x

5x - 2x = 3x
