Solve using quadratic formula. 2y^2-10y+8=0
2y%5E2+-+10y+%2B+8+=+0

2%28y%5E2+-+5y+%2B+4%29+=+2%280%29 ------- Factoring out GCF, 2

y%5E2+-+5y+%2B+4+=+0

Now solve this for y, using the quadratic equation formula: y+=+%28-+b+%2B-+sqrt%28b%5E2+-+4ac%29%29%2F%282a%29, where: matrix%281%2C4%2C+a+=+1%2C+b+=+-+5%2C+and%2C+c+=+4%29
