Question

a) 4x² = 16x
b) x ² + 10x = -25
c) 5x² = 125
d) 5x + x² - 24=0
e) -2x + x² =3
f) -9x + 3x² = 0
g) 4x² =100
h) 2x² =18
i) 10+ x²-7x=0
j) x² +6+ 5x = 0​

Answer 1

a) 4x² = 16x = x=4

b)x ² + 10x = -25 = x=-5

c) 5x² = 125= = x=5

d)5x + x² - 24=0= =x=3

e)-2x + x² =3= x=-1

f)-9x + 3x² = 0= = x=0
