If x₁ and x₂ are solutions of the quadratic equation, then we can write it in quadratic factorization:
a(x - x₁)(x - x₂)
We have x₁ = 5 and x₂ = 7
(x - 5)(x - 7) = (x)(x) + (x)(-7) + (-5)(x) + (-5)(-7) = x² - 7x - 5x + 35 = x² - 12x + 35
<h3>Answer: x² - 12x + 35 = 0</h3>
First the question is sayin that x will be substituted for -10
so for every x put -10
8(-10)=6(-10)-20
then you multiply to get the next expression
so you know that 6 times -10 =-60 and you know that 8 times -10=-80 so now you have
-80=-60-20
now you just solve so you would just subtract -60-20 which would equal -80
so your answer is -80=-80 which is true
