Help with Maths?
There’s a few questions from my maths homework which i’m stuck with. Please could someone help me?
Factorise:
1) 4 – 36x^2
Simplify:
1) x^2 – 1 / x + 1
2) 4y^2 – 9 / 4y + 6
3) 8yx / 6x^3 y^2 – 4xy^2
Express as a single fraction:
1) 4 / x^2 – 5 / x
2) 1 / ab + 1 / ac + 1 / bc
Solve using the formula correct to 2 decimal places:
1) x^2 + 7x + 2 = 0
2) 10y^2 – 6y – 15 = 0
3) a + 2 / a = a / 2a – 5
Thanks for the help

1. 4-36x^2
everything in the equation is a square, so square root everything. since the second number is negative, one of the two equations must also have the second number as negative. your answer is:
(2-6x) (2+6x)
sorry if i didn’t explain that well.
