2. 64y²+4y-3
3. 120x²+67-5

Answer 1

Answer:

1.x=-1/8 or -5/6

2.y=1/4 or -3/16

Step-by-step explanation:

1.48x²+46x+5

48x²+6x+40x+5

6x(8x+1)+5(8x+1)

(8x+1)(6x+5)

8x+1=0

8x=-1

x=-1/8

6x+5=0

x=-5/6

2.64y²+4y-3

64y²+16y-12y-3

16y(4y+1)-3(4y+1)

(4y+1)(16y-3)

4y+1=0

y=-1/4

16y-3=0

y=3/16
