One of the roots of the equation x²-5x +q=0 is 2. Find the other root and the value of the coefficient q.

yuradex [85]

Answer:

Other root: $x=3$

$q=6$

Step-by-step explanation:

If $x=2$ , then $x-2=0$ .

Therefore:

$x^2-5x+q=0$

$2^2-5(2)+q=0$

$4-10+q=0$

$-6+q=0$

$q=6$

This means that the other root is $x=3$ since $(x-2)(x-3)=x^2-5x+6$

I need step by step please 3(x-2)^2+1=13

Romashka-Z-Leto [24]

Answer:

$x_{1} = 0. \: \: \: x_{2} = 4$

Step-by-step explanation:

$3(x - 2)^{2} + 1 = 3$

$3( {x}^{2} - 4x + 4) + 1 = 13$

${3x}^{2} - 12x + 12 + 1 = 13$

${3x}^{2} - 12x + 13 = 13$

${3x}^{2} - 12x = 0$

$x \times (x - 4) = 0$

$x = 0$

$x - 4 = 0$

$\boxed{\green{x_{1} = 0. \: \: \: x_{2} = 4}}$
