If the absolute value of the difference between the two equations x2 + 2x + P = 0 is equal to 1, then p=

If the absolute value of the difference between the two equations x2 + 2x + P = 0 is equal to 1, then p=

Let two equations be α and β, then | α - β | = 1 √ [(α - β) & # 178;] = 1 (| a | = √ (| a |) √ [(α + β) & # 178; - 4 α β] = 1 ((a-b) & # 178; = (a + b) & # 178; - 4AB) (α + β) & # 178; - 4 α β = 1. According to Weida's theorem, α + β = - 2, α β = P, so (- 2) & # 178; - 4P = 14-4p = 3P =

The absolute value of the difference between the two equations x2 + 2x + P = 0 of quadratic equation 1 with one variable is equal to 1, and P is obtained
If two of the equations x2-ax-2 = 0 are X1 X2, then lx1l + lx2l = (l l l) is the absolute value
3 if the equation x2-2 (A-1) x - (B + 2) 2 = 0 has two equal real roots (1), find the power of A
+The cubic power of B (2) to solve the quadratic equation of one variable with the values of a and B as roots
When k is the value, the sum of squares of the two equations 2x2 - (4K + 1) x + 2k2-1 = 0 is 25 / 4
If one of the two real roots of the equation x2-4x-2m + 8 = 0 is greater than 1 and the other is less than 1, the range of M can be obtained

p=3/4
Square root of a ^ 2-4
A = 1, B = - 2, find the power of a + the third power of B = - 7

Given that a and B are real numbers and a ≥ 1, if the equation x & sup2; - 2bx - (a-2b & sup2;) = 0 has a real solution and satisfies 2A & sup2; - AB & sup2; - 5A + B & sup2; + 4 = 0. Find the value of a & sup2; + B & sup2

It is known that real numbers a, B, C, R, P satisfy pr > 1, pc-2b + RA = 0. It is proved that the quadratic equation AX2 + 2bx + C = 0 has real roots

It is proved that: 2B = PC + RA is known, so △ = (2b) 2-4ac = (PC + RA) 2-4ac = P2C2 + 2pcra + r2a2-4ac = p2c2-2pcra + r2a2 + 4pcra-4ac = (PC RA) 2 + 4ac (PR-1). PR-1 > 0 and (PC RA) 2 ≥ 0 are known, so when AC ≥ 0, △≥ 0; when AC < 0, △ = (2b) 2-4ac > 0. In conclusion, there is always △≥ 0, so the original equation must have real roots
