Question

how to solve this tell me

Answer 1

Solution 5.)

x^2 +49 + 14x

=> (x)^2 + (7)^2 + 2(x)(7)

=> ( x + 7) ^2

=> (x+7)(x +7)

[ a^2 + b^2 + 2ab = (a+b)^2]

Solution 6.)

16a^2 + 40ab + 25b^2

=> (4a)^2 + 2(4a)(5b) + (5b)^2

=> (4a + 5b)^2

=> (4a + 5b) (4a + 5b)

[ a^2 + b^2 + 2ab = (a+b)^2]

Solution 7.)

m^4 - 16m^2 +64

=> (m^2)^2 - 2(m^2) (8) + (8)^2

=> ( m^2 - 8)^2

=> ( m^2 - 8)(m^2 - 8)
