a2+9a+20 = (a+4)(a+5) when factored
The equation cannot be solved as there are two unknowns. However it can be simplified and the two unknowns (a and b) expressed in terms of the second unknown. 1) Expressing a in terms of b 4a + 2 = 3b - 5 4a = 3b -7 if desired this could be stated as a = (3b - 7)/4 2) Expressing b in terms of a 3b - 5 = 4a + 2 3b = 4a + 7 if desired this could be stated as b = (4a + 7)/3
No. It equals 15.
4a2 - 9a + 5 = 4a2 - 4a -5a + 5 = 4a(a - 1) - 5(a - 1) = (4a - 5)(a - 1)
4a+5=25 4a=25-5 4a=20 a=20/4 a=5
4a + a = 25 add 4a and a 5a = 25 then divide 25 by 5 a = 5
a=5
a=8 -5+4x8=27
The expression ( 9a + 4a - 5a ) can be simplified by combining like terms. Adding and subtracting the coefficients of ( a ), we get ( (9 + 4 - 5)a = 8a ). Therefore, the simplified expression is ( 8a ).
There is nothing you can do to 9a + 5 without knowing the value of a.
