Polynomial 3 / 8 (1-x & # 178;) What is the coefficient of X & # in?


-3/8



8(x+1)²-3(x+1)+2=0
solve equations


We regard (x + 1) as an unknown y, the original equation 8 (x + 1) &# - 3 (x + 1) + 2 = 0 will become 8y ^ 2-3y + 2 = 0, and y will have no real solution. Can the original equation also have no solution? We turn the original equation into a standard form
8x^2 +13x + 7= 0
△=13^2 - 4*8*7 < 0
The equation has no real solution
