Quadratic equations: factoring

2x2 +12x=32
2x2+12x-32=0 ( 2*32=64, 16*4=64.)
2x2 + 16x-4x-32=0
2x2-4x+16x-32=0
2x(x-2) +16(x-2)=0
(2x+16)(x-2)=0
x=-16/2 or x=2
{x=-8,2}

You must find the surface of the block therefore 98187 dived by 5628 = 583m squared

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
