Help?? With working out please

Mathematics
1 answer:
andriy [413]3 years ago
8 0

Answer:

Step-by-step explanation:

move all the terms to the right so your equation will equal 0. then look for the common denominator. which in this case is 60 (5*4*3).

multiply all terms by 60 then simplify.

12(2x-3)-15(6-3x)+120-20(7x)=0

24x-36-90+45x+120-140x=0

combine like terms and then divide

-71x=6

x=-6/71

(do not forget parenthesis when simplifying they are very important when it comes to distributing the minus sign)

Solve each equation by completing the square NEED THIS IN 10 MINS WILL GIVE BRAINLIEST
yulyashka [42]

Answer:

Step-by-step explanation:

7(b² - 2b - 8) = 0

7(b² - 2b +   ) = 8

7(b² - 2b + 1) = 8 + 1

7(b - 1)² = 9

(b - 1)² = 9/7

b - 1 = ±√(9/7)

b = 1 ±3√(1/7)

b ≈ -0.134, 2.134

m² + 10m + 14  = -7

m² + 10m +      = -7 - 14

m² + 10m + 25 = -7 - 14 + 25

(m + 5)² = 4

m + 5 = 2

m = -3

p² - 8p + 21 = 6

p² - 8p +     = 6 -21

p² - 8p + 16 = 6 -21 + 16

(p - 4)² = 1

p - 4 = 1

p = 5
