(08.02)the coordinate grid shows the plot of four equations.
which set of equations has (1,4) as its solution?
a and d
b and d
a and c
b and c

Your answer is B) B and D.

Step-by-step explanation:

If you look at the point (1,4), only two lines go through it.

Lines B and Lines D pass through points (1,4)

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
