What is the solution of the equation x squared = m squared?


x²=m²
x²-m²=0
(x + m) · (x-m) = 0 (square difference formula)
X = m or x = - M
Hope to help you with your problems!



Let X1 and X2 be the two roots of the square - (m-1) x-m = 0 (M is not equal to zero) of the equation x, and satisfy 1 / X1 + 1 / x2 = - 2 / 3
The solution of M


The relationship between rooting and coefficient
x1+x2=-[-(m-1)]/1=m-1
x1x2=(-m)/1=-m
So 1 / X1 + 1 / x2 = (x1 + x2) / x1x2 = - (m-1) / M = - 3 / 2
3m=2m-2
m=-2



The solution set of inequality (square of M + 1) x > 3 is


m²>=0
So M & # 178; + 1 > 0
So divide both sides by M & # 178; + 1
The direction of the unequal sign remains unchanged
So x > 3 / (M & # 178; + 1)



If the solution set of the square of inequality X - MX + n > 0 is X3, then M + n=


The solution set of the inequality x-mx + n > 0 is X3
So the root of the square of equation x - MX + n = 0 is 1 or 3
From the relationship between root and coefficient
1+3=m
1×3=n
That is, M = 4, n = 3
M + n = 7



On the inequality X2 - (2m + 1) x + M2 + m < 0 of X______ .


On the inequality of x 2 - (2m + 1) x + M2 + m < 0, that is, (x-m) (x-m-1) < 0, the solution is m < x < m + 1, so the answer is (m, M + 1)



How to do this type of problem. Inequality (square of m-2m-3) square of X - (M-3) X-1


Square of 1. M - 2m-3 = 0, M = 3 or M = - 1 (rounding)
The square of 2.. m-2m-3 is not the combination of numbers and shapes
Square of m-2m-3



If x-m > 1, the solution set of 2n-x > - 3 is 2


If x-m > 1, then x > m + 1;
2n-x > - 3, then x < 2n + 3;
M + 1 = 2, 2n + 3 = 19
The solution is m = 1, n = 8
So m + n = 9
The square root of M + n is ± 3
