2x2 - 10x + 8
2(x2 - 5x + 4)
2(X - 1)(X - 4)
==========zero factor rule
2(X - 1)
2X - 2 = 0
2X = 2
X = 1
=======agrees with above factoring

x^2-15=2xx^2-2x-15=0Once you get to this point, check to see if it can be factored. In this case, it can be factored into (x-5)(x+3)=0.Therefore, x= 5 and -3
You need to solve x before I can answer this
3xx + 2 + xx + 4 = 4xx + 6 = 2(2xx + 3)
x=6Solution:x + 2x + 14 = 5x + 214 - 2 = 5x - 3x12 = 2xx = 12/2 = 6
i think the answer is 1 X2+2xX-1 X=1 x times x = 1 plus (X times x) = 1 1+1 equals 2 minus one = 1Whoever above is, is wrong. the actual answer is X^(2)+2X-1: The part showing '^(2)' means to the power of two or squared on a computer.
