10 squared equals 100. 102 = 10*10 10*10 = 100
h/(-3 - 7) = 10h/-10 = 10h = -100

You fill in for x and solve the equation3(5)^2 - 2(5)15^2 - 10; now solve
(3x-2)(x-2)
1566 = x
(x-5)(x+3)
2x+8x-2=22 10x-2=22 10x+2=+2 10x=24 10/10=24/10 x=2.4
10 squared equals 100. 102 = 10*10 10*10 = 100
x2-10 = 4x+11 x2-4x-10-11 = 0 x2-4x-21 = 0 (x+3)(x-7) = 0 x = -3 and x = 7
7a=2(-10)........................................answer is 20/7
h/(-3 - 7) = 10h/-10 = 10h = -100
X squared - 3x - 10 = 0 (x-5) (x+2) = 0 x - 5 = 0 x + 2 = 0 X= 5 x = -2
-10x = -50 Divide both sides by -10 remembering that a minus divided by a minus the quotient then becomes positive: x = 5 So: -10*5 = -50
