62 tens is the same as 62 x 10: 62 x 10 = 620
"10x - x" is basically 10 x's minus one x. The answer is 10 minus 1, but in terms of x. Since 10 minus 1 is 9, the answer is 9x.
9x+6=51 9x = 45 x= 5 9x-6=51 9x = 57 x= 6.33
9x-53=6/x 9x2-53x=6 9x2-53x-6=0 9x2+x-54x-6=0 x(9x+1)-6(9x+1)=0 (9x+1)x(x-6)=0 9x+1=0 or x-6=0 9x=-1 or x=6 x=-1/9 or x=6
3x2 + 27x = 30 ∴ x2 + 9x - 10 = 0 ∴ (x + 10)(x - 1) = 0 ∴ x ∈ {-10, 1}
f(x) = x^2 - 9x - 10 = ( x - 10 ) ( x + 1 )Answer : ( x - 10 ) ( x + 1 )
Step 1: Divide by 9x: 9x (x2 + 3x - 10) = 9x(x + 5)(x - 2)
9x2 - 28x + 20 = 9x2 - 18x - 10x + 20 = 9x(x - 2) - 10(x - 2) = (9x - 10)*(x - 2)
(x - 10)(x + 1)
2x2 + 10 = 9x 2x2 - 9x + 10 = 0 (x - 2)(2x - 5) = 0
2x2 + 10 - 9x = 0 or 2x2 - 9x + 10 = 0 So (x - 2)*(2x - 5) = 0
62 tens is the same as 62 x 10: 62 x 10 = 620
If x equals 10 and y equals 10, then 9x plus 8y equals 170.
2x2 - 9x + 10 = 2x2 - 4x - 5x + 10 = 2x(x - 2) - 5(x - 2) = (x - 2)(2x - 5)
I suppose you mean, how do you factor it. 7x2 - 9x - 10 = (7x + 5)(x - 2).
Once upon a time: 9x-10 = 80 And then at the end: x = 10
8 - 3x = 9x - 10 +3x +3x______________8 = 12x - 10+10 +10______________18 = 12x__ ___12 123/2 = x, or x = 1.5
