Correct He made a mistake. Each quadratic equation must have two solutions. He "overlooked" one solution.

Step-by-step explanation:

Given:

x² - 6 x - 7 = 0  ⇒ x² - 2 · x · 3 + 3² - 3² - 7 = 0

the first three members form a complete the square of the binomial.

(x - 3)² - 16 = 0  ⇒ (x - 3)² - 4² = 0

now we get the square difference

(x - 3 - 4) · (x - 3 + 4) = 0 ⇒ (x - 7) · (x + 1) = 0

x - 7 = 0  or  x + 1 = 0  ⇒ x₁ = 7  or  x₂ = - 1

x₁ = 7  or  x₂ = - 1

God is with you!!!

Step-by-step explanation:

no its wrong what mistake john did ishe should remove the square function from both lhs and rhs..

as x-3=4

then he should procced next

hope it helps you

it depends on the weather. because i have flown to seattle when it was pouring down rain and there was one time i flew to ohio when it was snowing hard. whats your situation.

step-by-step explanation:

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
