Write x^2 - 6x + 7= 0 in the form (x-a)^2 b, where a and b are intergers.

dimaraw [331]

Answer:

(x-3)^2=2

Step-by-step explanation:

${x}^{2} - 6x + 7 = 0 \\ adding \: 2 \: both \: sides \\ {x}^{2} - 6x + 7 + 2 = 0 + 2 \\ {x}^{2} - 6x + 9 = 2 \\ {x}^{2} - 6x + {(3)}^{2} = 2 \\ (x - 3) ^{2} = 2$

If discriminant (b^2 -4ac>0) how many real solutions

MaRussiya [10]

Answer:

If Discriminant, $b^{2} -4ac >0$

Then it has Two Real Solutions.

Step-by-step explanation:

To Find:

If discriminant (b^2 -4ac>0) how many real solutions

Solution:

Consider a Quadratic Equation in General Form as

$ax^{2} +bx+c=0$

then,

$b^{2} -4ac$ is called as Discriminant.

So,

If Discriminant, $b^{2} -4ac >0$

Then it has Two Real Solutions.

If Discriminant, $b^{2} -4ac < 0$

Then it has Two Imaginary Solutions.

If Discriminant, $b^{2} -4ac=0$

Then it has Two Equal and Real Solutions.
