Sagot :
solution - x=1/10a2+21/10
swap the side - a2+21=10x
divide both side - 10x=a2+21
a² + 21=10x value of a,b,c
standard form: a² - 10x + 21 = 0
a = 1
b = - 10
c = 21
x² - x=6 standard form and value of a,b,c
standard form: x² - x - 6 = 0
a = 1
b = - 1
c = -6
standard form: a² - 10x + 21 = 0
a = 1
b = - 10
c = 21
x² - x=6 standard form and value of a,b,c
standard form: x² - x - 6 = 0
a = 1
b = - 1
c = -6
