This isn't an equation, if you meant factor:
2a%5E2%964a%9670 factor out the GCF 2
2%28a%5E2-2a-35%29
2(a___)(a____) the blank needs to be filled with two numbers that = -35 when multiplied and add to give you -2. -7*5=-35 and -7+5=-2
highlight%282%28a-7%29%28a%2B5%29%29
If you really meant to type 2a^2-4a-70=0, we can now solve it.
2%28a-7%29%28a%2B5%29=0
2%28a-7%29%28a%2B5%29%2F2=0%2F2
%28a-7%29%28a%2B5%29=0
a-7=0 and a+5=0
a=7 and a=-5
Happy Calculating!!!
