Question

4 Math Questions 1.) a^2-10a=4 2.) x^2+20x-18=3 3.) (x-5)^2=1 4.) x^2-18x=65

Answer 1

1) a=5+√29 or a=5−√29 2) x=1 or x=−21 3) x=4 or x=6 4) x=9+√146 or x=9−√146 Hopefully that helps you ❤

Answer 2

1) a^2 -a^1 = 4/10
a = 2/5

2)x^2 + 20x = 3+18
x^2+x^1 =21/20
x=21/20

3)(x -5) (x-5) = 1
x^2- 5x -5x+25 = 1
x^2-10x = 1-25
x^2-10x= -24
x^2-x^1= -24/10
x=-12/5 (2/2/5)

4)x^2 -x^1 =65/18
x =3/11/18
