(9 - y)(a + 5)
(9 - y)(a + 5)
y2-y-72 is an algebraic expression that can be factored as: (y+8)(y-9)
-9
Y=-1
(9 - y)(a + 5)
(9 - y)(a + 5)
y + 9
y squared minus 9 (y*y)- 9 cannot be solved because there is no given value for 9.
3x-y=9 y=3x-9
y2-y-72 is an algebraic expression that can be factored as: (y+8)(y-9)
-9
What is 1/2 of four times Y plus the quantity of Y and 3
9x2 - 6xy + y2 - 81 = (3x - y)2 - 81 = (3x - y - 9)*(3x - y + 9)
9x2 - 6xy + y2 - 81 = (3x - y)2 - 92 = (3x - y - 9)(3x - y + 9)
5(x + y)
meaning to multiply something into a term x. for example, this term x can be (3+a), or even (a+b+c+8). let us name that something 'y'. to expand, we put y(x), meaning y times x. another example, -g(a) = -ag, or minus (a times g). if the set x contains more than one term, multiply all the terms by y. y(a+b) = ay + by.remember, minus times minus is a plus, and minus times plus is minus.
