4x² + 2x - 30 = 0
<span>
factor out the GCF:
</span>2(2x² + x - 15) = 0
<span>
factor the trinomial completely:
2x</span>² + x - 15 = 0
2x² + 6x - 5x - 15 = 0
2x(x + 3) - 5(x + 3) = 0
(2x - 5)(x + 3) = 0
<span>use the zero product property and set each factor equal to zero and solve:
2x - 5 = 0 or x + 3 = 0
2x = 5 x = -3
x = 2.5
</span><span>The roots of the function are x=-3, x=2.5</span>
Answer: Imagine being mad for not getting an answer
Step-by-step explanation:
Factor by grouping, -x2y2+9y2= y2(-x2+9)
x4-9x2=- x2(-x2+9)
= (y2-x2)(-x2+9)
Step-by-step explanation:
5=(6y+9)
5-9=6y
-4=6y
-4/6=6y/6
y=-4/6
Answer:
<h3> <u>
M(3; 4)</u></h3>
Step-by-step explanation:
(2,4) and (4,4)
The midpoint is M(xM; yM).
xM=(x1+x1)/2=(2+4)/2=3
yM=(y1+y2)/2=(4+4)/2=4
=> <u>M(3; 4)</u>
