Question

factorise the quadratic equation 2b²+10b+12=0​

Answer 1

Answer:

b= -3 and b= -2

Step-by-step explanation:

= 2b²+10b+12=0

Divide both sides by 2.

= b²+5b+6 = 0

= b²+3b+2b+6 = 0

= b×(b+3)+2b+6 = 0

= b×(b+3)+2(b+3) = 0

= (b+3) (b+2) = 0

= b+3 = 0 and b+2 = 0

= b = 0-3 and b = 0-2

= b= -3 and b = -2

•°• The values of b are -3 and -2.
