4y2+16y+16=0 Divide by 4 on both sides: y2+4y+4=0 Factorise: (y+2)(y+2)=0 Therefore y= -2
4y2 + 16y + 16 = 4(y2 + 4y + 4) = 4(y2 + 2y + 2y + 2) = 4[y(y + 2) + 2(y + 2)] = 4(y + 2)2
11y + 16 + 5y = 16y + 16 = 16(y + 1)
If: -8y-7 = -8+8y Then: -7+8 = 8y+8y And: 16y = 1 So: y = 1/16
16y = x or more properly y = x/16
4(y + 2)(y + 2)
4y2+16y+16=0 Divide by 4 on both sides: y2+4y+4=0 Factorise: (y+2)(y+2)=0 Therefore y= -2
4y2 + 16y + 16 = 4(y2 + 4y + 4) = 4(y2 + 2y + 2y + 2) = 4[y(y + 2) + 2(y + 2)] = 4(y + 2)2
11y + 16 + 5y = 16y + 16 = 16(y + 1)
If 4*y*2+16*y+16: 8y+16y+16 24y+16 8(3y+2) -------------------------------------------- If 4*y**2+16*y+16: 4(y**2+4y+4) in ay**2+by+c: a=1 b=4 c=4 the multiples of b are: 1*4 2*2 the multiples of b that adds up to c is 2*2 4(y+2)(y+2) 4(y+2)**2
Replace the y with a 3. 16 x 3 + 9 = 57
16y = 164 y = 164/16 = 82/8 = 41/4 = 10.25
If: -8y-7 = -8+8y Then: -7+8 = 8y+8y And: 16y = 1 So: y = 1/16
16y = x or more properly y = x/16
You plug in the values of x and y and solve 12x + 16y = ? 12(1) + 16(2) = 12 + 32 = 44
It is -96x -96y.
4x + 16 + 1 = 4x + 17 which cannot be factorised.
