Factor 4y2 plus 16y plus 16?
4(y + 2)(y + 2)
What is y in x equals 4y2 plus 6 when x equals 42?
In the equation x = 4y2 + 6 where x = 42, we need to substitute 42 for x and solve for y. x = 4y2 + 6 42 = 4y2 + 6 42 - 6 = 4y2 + 6 - 6 36 = 4y2 36 / 2 = 4y2 / 2 18 = 4y 18 / 4 = 4y / 4 9 / 2 = y 4 1/2 = y (or 4.5 = y)
What is 4y2 plus 16y plus 16?
4y2+16y+16=0 Divide by 4 on both sides: y2+4y+4=0 Factorise: (y+2)(y+2)=0 Therefore y= -2
4y2 - 44y plus 121?
(2y-11)^2
