X^2 - 7x = 0
Factoring:-
x(x - 7) = 0
x = 0' x - 7 = 0 so x = 7
Solution is 0, 7.
Answer:
C 3x + 12
Step-by-step explanation:
3(x + 4)
The 3 gets distributed to each term inside the parenthesis
3(x + 4) = 3x + 3*4
3(x + 4) = 3x + 12
No, this means she has 2 times 14 total. if she does 28/2 she will get 14. she has $14 left.
The greatest common factor is 5x^2 so:
5x^2(x^2-1) (now notice that the parenthetical term is the difference of perfect squares)
The rule for factoring difference of squares is: a^2-b^2=(a-b)(a+b) so:
5x^2(x+1)(x-1)
