x+(-2.5)+6.8=0
x+(-2.5+6.8)=0
x+(4.3)=0
x+4.3=0
Subtract 4.3 from both sides and you get:
x= -4.3

What is x squared minus 5x plus 25 over 4 equals zero in quadratic form?
It is, as stated, x2 - 5x + 25/4 = 0
How many x-intercepts does the graph of y equals 9x2 plus 30x plus 25 have?
Factorising, we have, 9x2+ 30x + 25 = (3x + 5)2;thus, when y = 0, x = -1⅔. This tells us that the sole x-intercept of this function is at the vertex, (0, 1⅔).
What does 1x plus 1 plus x equals 1 equal?
