Answer:
1. x=5 or -3
Step-by-step explanation:
1. 3x²-6x-45
since all can be divided by 3, u will divide all by three.
the result will be
x²-2x-15=0
x²-5x+3x-15=0
x(x-5)+3(x-5)=0
(x+3)(x-5)= 0
x+3=0 or x-5=0
x=-3 0r 5.
2. 4x²+24x=-35
4x²+24x+35=0
4x²+10x+14x+35=0
2x(2x+5)+7(2x+5)=0
(2x+7)(2x+5)=0
2x+7=0
x=-7/2
2x+5=0
x=-5/2
there fore x=-7/2 or -5/2
