Aschool has 400 chairs to put in the gymnasium of their school for a concert. the school wants to set up the chairs so that they have the same number of chairs as there are rows. how many rows will there be? how many chairs will be in each row? explain how you know in 3-5 sentences.

all work is shown and pictured

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
