X plus 5 minus 2 for x equals 9?
x + 5 - 2x = 9 -x = 4 x = -4
Can someone please solve the square root of x plus 5 minus the square root of x minus 5 equals 2?
root(x+5)-root(x-5)=2 root(x+5)=2-root(x-5) x+5=4-4root(x-5)+x-5 4root(x-5)+6=0 root(x-5)=-3/2 x-5=9/4 x=9/4 +5 x=29/4
How do you solve x squared minus 4x minus 5 equals 0?
X2 - 4X - 5 = 0 easy factor, what two factors of - 5 add up to - 4 (X + 1)(X - 5) X = - 1 ------------- X = 5 --------------
What is 4 over x plus 4 minus 2 over x plus 1?
2/x + 5
Is 0.0000115 minus 4 to the power?
0.0000115 = 1.15 X 10 -5 ---------------------is this what you mean? Not - 4 but - 5 .
What is 3 over x minus 5 minus 4 over 5 minus x in lowest terms?
3/x-5 - 4/5-x 3(5-x) -4(x-5) 15-3x-4x+20 35-7x
What is x squared minus x minus 20?
(x - 5)(x + 4)
X squared minus x minus 20?
(X-5)(X+4)=0 so X-5=0 -----X=5 and X=4=0 so X=-4 it factors to (X-5)(X+4) so X=5,-4
