Question

(4х-3)(5х+8)=0,(-7х+4)(8x-9)=0 пж помогите

Answer 1

(4x-3)(5x+8)=0

4x-3=0
5x+8=0

x=3/4=0,75
x=-8/5=-1,6


x1=-1,6
x2=0,75


(-7x+4)(8x-9)=0

-7x+4=0
8x-9=0

x=4/7
x=9/8=1,125

x1=4/7
x2=1,125

Answer 2

1) (4х-3)(5х+8)=0

4х-3=0

5х+8=0

х1=-8/5

x2=3/4

2) (-7х+4)(8х-9)=0

-7х+4=0

8х-9=0

х1=4/7

х2=9/8
