Help me please!!!!!!!!

Mathematics
1 answer:
lidiya [134]2 years ago
5 0

Step-by-step explanation:

Step 1: Subtract -8 from both sides.

x2+4x−40−(−8)=−8−(−8)

x2+4x−32=0

For this equation: a=1, b=4, c=-32

1x2+4x+−32=0

Step 2: Use quadratic formula with a=1, b=4, c=-32.

x=−b±√b2−4ac2a

x=−(4)±√(4)2−4(1)(−32)2(1)

x=−4±√1442

x=4 or x=−8

Answer:

x=4 or x=−8 = The first one

Find the missing term (need help)
katen-ka-za [31]

Answer:

x² - 10x + 34

Step-by-step explanation:

given the roots are x = 5 ± 3i then the factors are

(x - (5 + 3i))(x - (5 - 3i))

= (x - 5)² - 9i² ← expand (x - 5)²

= x² - 10 x + 25 + 9 → [ i² = - 1 ]

= x² - 10x + 34

the missing term is 10x

Its only one math question show right steps then get brainliest and right answer ofc
valkas [14]

Step-by-step explanation:

equation.

2(m+10)=4(m−15)

(2)(m)+(2)(10)=(4)(m)+(4)(−15)(Distribute)

2m+20=4m+−60

2m+20=4m−60

Step 2: Subtract 4m from both sides.

2m+20−4m=4m−60−4m

−2m+20=−60

Step 3: Subtract 20 from both sides.

−2m+20−20=−60−20

−2m=−80

Step 4: Divide both sides by -2.

−2m−/2=−80/−2

m=40
