Question

If a+b=9 and ab= -22 find a square- b square

Answer 1

Answer:

$a1 = 11 \: \: or \: \: b1 = - 2$

&

$a2 = - 2 \: \: or \: \: b2 = 11$

Step-by-step explanation:

$a = 9 - b \: \: \: \: ....(equation \: 1)$

put the value of a in equation ab = -22

$(9 - b)b = - 22$

Solve the equation for b, we get

$b1 = - 2 \: \: or \: \: b2 = 11$

Put the value of b1 and b2 in equation 1 , we get

$a1 = 11 \: \: \: or \: \: a2 = - 2$
