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

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.  

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet
