There is nothing here for anyone to work off, If you have a picture or screenshot that would be very nice!
hello :
<span>help :
<span>the discriminat of each quadratic equation :
ax²+bx+c=0 ....(a ≠ 0) is :
Δ = b² -4ac
1 ) Δ > 0 the equation has two reals solutions : x =
(-b±√Δ)/2a</span>
2 ) Δ = 0 : one solution : x = -b/2a
3 ) Δ < 0 : no reals solutions</span>
I’m not too sure of what you are asking. But if you want an equivalent expression, it would be
7(2k+5)
Since 7 is the greatest common factor of both 14 and 35. 14/7=2. 35/7=5
