Question

2)Factorise
2x²+7x+3 (3)
3)Write four solutionsfor 2x+y=8. (2)
4) If two lines intersect each other then prove that the vertically opposite angles are equal.

#Answer. ​

Answer 1

X^2 + 7x + 3

=4 thank you

that is the best thing

Answer 2

Answer:

2) 2x²+7x+3

—> 2x² + 6x + x + 3

—> (2x + 1) (x + 3) = 0

—> x = -1/2 , -3

_____________________

3) 2x+y=8

—> y = 8 - 2x

i) if x = 0

y = 8

ii) if x = 1

y = 6

iii) if x = 2

y = 4

iv) if x = 3

y = 2
