Question

the zeros of the X square + 7 x + 10 are _____ and _____

Answer 1

x^2+7x+10
x^2+2x+5x+10
x(x+2)+5(x+2)
(x+2) (x+5)
zeroes are:
-5,-2

Answer 2

Answer:

x² + 7x + 10

x² + 7x + 10 = 0

= x²+ 2x + 5x + 10 = 0

= x ( x + 2 ) + 5 ( x + 2 ) = 0

= ( x + 2 ) ( x + 5 ) = 0

= x + 2 = 0 (or) x + 5 = 0

= x = –2 (or) x = –5

= x = –2 and – 5

The zeroes of the x² + 7x + 10 are –2 and –5 .

Hope it helps
