Can i have some help in this? 1.-5(-4p-3)>-105
2.-141 ≥ -4(6r-8)-5
3.3(a-4)≥ 5-(3a-1)
4.7(m-1)≥ -7m+3(4m-7)

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0

good luck on ur quiz test or homework. have a good day : )
