Hi there!
We can find the answer by factoring the equation, then setting them up equal to zero.
x² - 7x + 12 = 0
(x - 3)(x - 4) = 0
x - 3 = 0 x - 4 = 0
x = 3 x = 4
So you have two real solutions for the equation x² - 7x + 12 = 0.
Hope this helped! :)
The slope is 2 because after u use the slope formula u get 4/2 which reduces to 2
(6a+10)⋅(3a+55)=18a^2+330+30a+550
=18a^2+330a+30a+550=18a^2+360a+550
a=-5/3 or a=-55/3
hope it helps!
